Almost Bored

Yesterday started off with a great breakfast. Donna cooked sunny-side-up eggs for me in the Pampered Chef microwave egg cooker our friend Mona gave us. She served it with cilantro and avocado over skirt steak strips with salsa on the side.

I puttered around most of the day. I’m still resting my sore shoulder, so that means no bicycling or anything strenuous. I need to get on the roof to clean and polish the crown where the roof meets the side walls of the coach. I hope I can do that next week. I don’t want to lift the ladder and climb it right now. For the first time since we hit the road, I’m getting a little bored, sitting around and waiting for my injury to heal.

FedEx delivered a couple of items I ordered through Amazon from Ryder Fleet Products. I bought new wiper inserts. The wiper blades on the coach are dry and cracking. That’s common in the southwest from sitting in the sun. My neighbor, George, gave me wiper blade covers to protect them when I install the new inserts.The covers are a mesh cloth that wraps around the blade and are held in place with velcro strips. They’re supposed to filter the sunlight and keep the blades cooler. I want to be sure we have good wipers when we hit the road. We could drive into a thunderstorm anytime, any place.

I also ordered two fuel filter/water separators. Diesel engines need a clean fuel supply. Filtration is necessary. Water can build up in the fuel tank from condensation. Any time we will be sitting in one place for more than a week, I try to have the tank as full as possible. With less air space in the tank, the chance of condensation forming is reduced.

The Fleetguard external fuel filter on our coach is also a water separator. It has a sensor on the bottom that plugs into a wiring harness on the coach. If we have excess water, it will illuminate a warning light on the dash. It also has a drain port on the bottom. The water will separate from the fuel in the bottom of the filter canister. Opening the drain will allow the water to run out.

Water in the fuel can cause corrosion in the fuel system. The other problem with water in the fuel is the formation of algae. Once this happens, it clogs the fuel filter and is hard to eradicate. I haven’t worried about it too much while we’re parked here in the dry desert air and I haven’t had to drain any water from the filter. However, once we start our travels again, I’ll start adding an algaecide additive to our fuel tank.

The water separator is in the service bay – the last bay on the right rear of the coach. This service bay allows access to the fuel filter, air filter and air filter restriction gauge, engine oil dipstick, transmission fluid dipstick, air suspension water drain and various relays and fuses.

Last week I opened the air filter housing to look at the air filter. It looks okay and the restriction gauge shows 8 inches vacuum (H2O) – almost no restriction. I won’t replace the air filter element until the gauge reads above 20 inches H2O. Replacing air filters too soon isn’t a good idea. New air filters don’t have as much filtration efficiency as one that has already trapped some particulate matter. The trapped particulates act as added filter media. With the vacuum gauge set-up in the service bay, I’ll know exactly when we need to replace the air filter element.

I’ll replace the fuel filter/water separator next week, before we leave here. I don’t know for sure how old the current filter is. Barring any contamination issues, replacing the fuel filter/water separator will become an annual maintenance item. I ordered two of them so I can carry a spare on the road. If we get a tank of contaminated diesel fuel, I can change the filter on the side of the road.

Last evening, Donna and I had dinner at Red, White and Brew. Then we drove over to DNA Cycles to pick up Donna’s bike (she rented a car for the weekend). Afterwards, we came home and I watched the NCAA basketball tournament. Both Michigan and Michigan State advanced to the Elite Eight round. Dayton is in as well. San Diego State was eliminated Thursday night. Sunday’s games will determine the final four. This is my favorite basketball tournament.

I hope whatever is wrong in my left shoulder heals soon, so I can get some things done and quit moping around.

Under Pressure

Yesterday, the temperature stayed in the upper 70s – much cooler than the days before. Today is forecast to warm up back into the 80s. I’ll pull the window awnings out to shade the windows again since we don’t expect much wind.

I haven’t been very active the last few days. I’m resting my shoulder, hoping that whatever is wrong with it will heal. I’ve been spending too much time in the coach though. I finished reading A Thousand Splendid Suns by Khaled Hosseini, the author of The Kite Runner. Donna and I watched that movie again Wednesday night. She was bawling.

While I was sitting at the table yesterday, I looked out the window. A covey of quail were walking through our site. There were five or six of them. They seemed curious about our scooter. Two of them stopped under it and looked around. Then they climbed on the muffler and jumped onto the rear tire. One crawled through the engine compartment.  Another jumped onto the floorboard, then hopped on the seat. I tried to take a couple of pictures. I knew they would scurry away if I opened the door, so I shot through the window glass. The window glass created a moire effect, but there wasn’t anything I could do about it. The photos are poor, but I’ll share them anyway.

This one wanted to take it for a ride.

Speaking of the scooter, Donna was going to ride it over to the optometrist to pick up her prescription and go grocery shopping. I told her I should check the tire pressure before she rode it, since I haven’t checked it for a few weeks. It’s not unusual for tires to lose 1 or 2 psi per month.

I try to keep our tires properly inflated. Under-inflated tires are the leading cause of tire failure, such as blow-outs. Improper inflation can also cause poor handling, increased wear and decreased fuel mileage. It’s not as easy to fill tires at gas stations as it used to be. Back when gas stations were full-service stations, there were hoses with air chucks next to the gas pump. You could inflate your tires for free while the gas was being pumped. It still only takes a few minutes though and it’s an important task that too many people neglect.

The tires on the scooter were down a couple of pounds. I got the Porter-Cable portable air compressor out of the basement compartment and filled the tires to the proper pressure. I also use this compressor to fill the tires on our coach. The front tires on our coach are inflated to 110 psi. This little compressor produces a maximum of 150 psi. The pump cuts in when the pressure drops to 125 psi, so the pressure is always high enough to fill a 110 psi tire.

Proper tire inflation is important when you only have two wheels under you. It’s also very important when you are driving a 40-foot, 30,000-plus-pound motorhome. Having said that, let me add that it’s important no matter what vehicle you are driving. Please take a moment out of your day and check your tire pressures. This might help you avoid problems down the road.

Last night, Donna prepared pork tenderloin with a new marinade. It was a ginger-soy-sherry marinade and it was really tasty. I grilled it along with asparagus spears and she baked a big sweet potato that we shared. Yum.

Today, I think I’ll check the library in the clubhouse and see if I can find an interesting book to read. Then, I’ll relax at the pool and read it.

 

Car Nuts and Volts

Yesterday I was moving rather slowly. I pinched a nerve in my neck, probably an overuse issue from washing and waxing the coach with my arms up and my head tilted back. After I posted to the blog, I ordered a small pizza to go from the Red, White and Brew.

I spoke to Donna on  the phone. She was on her way home from Albany, New York and waiting for a connecting flight in Chicago. Everything seemed to be on schedule. I was looking forward to her return home around 8pm.

When I picked up the pizza, I remembered there was a car show down the street from us at the Apache Wells Community Center. After lunch, I scootered over to the show.

I didn’t know what to think of this next one – it’s a motorcycle with a side car powered by an inline 6-cylinder car engine.

I spent about an hour looking at the cars. Then it was time to get stuff done.

When I returned to the coach, I thought I should take a look at the 6-volt battery bank that powers the house 12-volt system. We have a bank of four 6-volt deep-cycle golf cart batteries. These are flooded, wet cell type lead/acid batteries. The batteries are wired in pairs. Each pair is wired together in series – positive to negative. In effect, this creates a big 12-volt battery. Then the two pairs are connected together in parallel – positive to positive and negative to negative. This creates an even bigger 12-volt battery. Wiring in series makes the voltage additive; i.e., 6 volts plus 6 volts equals 12 volts. Wiring them in parallel makes the capacity (amp hours) additive, but voltage remains constant.

Our battery bank – the four golf cart batteries are wired together. The two 12-volt batteries in the left rear are starter batteries.

The flooded wet cell 6-volt batteries require maintenance. Our inverter charges the batteries when we are on shore power or when we run the generator. The electrolyte in the battery is 35% sulfuric acid and 65% water. The water will evaporate when the battery is being charged. Periodically you need to remove the caps and look at the electrolyte level. The lead plates inside each cell must always be completely submerged in electrolyte. If the plates are exposed to air, they will be damaged.

If you need to add water, you need to use distilled water. Tap water or drinking water contains minerals that will build up and eventually short the plates. Never add more electrolyte to a battery. Only the water evaporates, so only distilled water needs to be added. I use a turkey baster to add distilled water to each cell.

I need to clean the dust off the batteries. That’s a chore for another day.

Donna made it home around 8pm. She had a great trip. She says the housewares show in Chicago was amazing and she met with some interesting people including a buyer for the Camping World catalog and representatives from the Home Shopping Network and QVC. I’ll share some of the goodies she brought home tomorrow. She also enjoyed visiting her parents who live west of Albany, New York. From all accounts, they are both doing very well although, like most people in the Northeast, they are ready for winter to be over!

We watched an old Quentin Tarantino movie called Jackie Brown last night. Donna was jet-lagged and barely stayed awake to the end.

 

 

 

 

 

A Polished Set

I didn’t pick up Donna’s bike yesterday. She needs to replace her rear wheel and is deciding what she wants to do about it. I took advantage of having Mike Hall’s Jeep by making a Costco run. I stocked up on bottled water, coffee k-cups and a three-pound bag of Japanese rice crackers with nuts, one of my favorite snacks.

I started the wash and polish job around 11:30am. After I washed the front and right side, I got the ladder out and cleaned the windows. While I was drying the coach, our neighbor, George, came over. He offered to lend me his fiberglass ladder. He said the steps on it were bigger and thought it would be easier on my feet and back. I took him up on it, but it turned out not to be tall enough for me to reach to the roof line.

I worked at it nonstop until 3pm. In hindsight, it may have been smarter to break it up into two sessions. The thing is, once I get started on a project like this, I want to get it done. I don’t want to sound like a wimp, but by the time I finished, I could barely raise my arms and I had pain running from my neck to my left shoulder. I don’t know what that’s all about, but it’s still sore this morning. The coach looks great though!

After I showered, I called Mike Hall to see when he wanted me to drop off the Jeep. We decided to put it off until this morning.

Last evening was the Apache Wells RV Resort Farewell dinner party. They do this every spring as a thank you to all of the snowbird guests who spend the winter here. Most of the snowbirds will be heading back north over the next two weeks. They had tables under canopies set up in the street by the office. The street had been closed for the last two days as preparations were being made. Park exit and entry was through an alternate gate north of the main entrance (which was closed).

They served beef tips in sauce over egg noodles. Not a gourmet treat, but you can’t beat the price. It was free!

After dinner, a band set up on a stage in the street, near the park entrance. The band was called Johnny K and Kompany. They played songs from the 50s and 60s. The front man was an excellent singer. Their playlist included songs that ranged from Nat King Cole to the Searchers (Love Potion #9). They really had the crowd going when they played Ghost Riders in the Sky – a cowboy song penned in the 40s by Stan Jones and covered by everybody from Dick Dale to Johnny Cash to the Marshall Tucker Band.

The band sounded great – their songs were polished. I had enough by the second set and went back to the coach. I was whipped from the day’s work.

Today I want to check out a set of bicycle race wheels that Donna’s friend, Dara offered her. If they’re suitable for Donna’s needs, it will be a good deal. Donna already put $300 into the tune-up which included new cables, chain and gear cassette. I also need to return the Jeep and retrieve the scooter.

 

 

Never a Dull Moment

Yesterday, I continued my wash and wax project. I forgot to mention yesterday that when my neighbor told me his Jeep wouldn’t be in the driveway, he also said a park worker stopped him from washing his Jeep and told him it wasn’t allowed. He thought I might get in trouble for washing my rig in the RV park.

I thought that was strange. This park (Apache Wells RV Resort) is owned by Cal-Am Resorts. They also own the Sun Life RV Resort where we stayed in January. I saw people washing their RVs at Sun Life. I didn’t think Cal-Am would have different rules at another resort a few miles away in the same city. I looked up their policy. The policy states that “washing of automobiles is prohibited within the resort.” It goes on to say that there are many establishments in the area for car washing.

My take on the policy is this: if you have a passenger car or pick-up truck that you can drive to a car wash, you can’t wash it here. I don’t see that as prohibiting anyone from washing a motorhome or trailer.

I got an early start. I was washing the driver’s side of the coach by 8:30am. After I cleaned the windows and dried the surface, I polished the entire left side of the coach. This is a large area to apply polish to and then buff. I finished right at noon. The results look to be worth it.

The polymer polish/protectant product I’m using is easy to apply and also buffs out easily. I’ll wait to see how well it holds up before I make a recommendation for this stuff.

In yesterday’s post, I laid out a general plan for our travels in the year ahead. My friend and former colleague, Allen Hutchinson commented that he would be competing in the Ironman Triathlon in Coeur d’Alene, Idaho at the end of June. We’ll be in Great Falls, Montana the week before for Donna’s bicycle race. Coeur d’Alene is only a little more than three hundred miles away.

We’ll book a site in Coeur d’Alene and hook up with Allen and his family. Maybe this time I can see him finish the race! I wrote about missing him at the finish of the Lake Placid Ironman here. That’s the beauty of this nomadic lifestyle. We get to catch up with friends when our time and space coincides!

Yesterday, Donna called and said she received a message from the bike shop. They said they’d found cracks in the rim of her rear wheel. I scootered over to the shop and looked at the wheel. In three places, where the spoke nipple passes through the rim, there were cracks. The wheel will have to be replaced. Donna’s figuring out her best option for a new wheel.

I had already arranged to borrow Mike Hall’s Jeep to pick up Donna’s bike. I went ahead and got the Jeep from Mike. I wanted to go to the Handlebar Pub and Grill in Apache Junction to watch the String ‘Em Up Band perform bluegrass music. I met Andy King there.

Andy is my friend from our high school days. He was a member of the String ‘Em Up Band, but now he just sits in for a set or two from time to time. I ordered a mushroom burger and ate while the band set up.

The second set was really interesting and fun. It was like an open mic session. First, a harmonica player from the audience joined the band. He was good. He fit right in with fills and solos on the harmonica. Then a young man (I want to say a kid, but he was at least 21 years old) stepped in. He sang an original composition and played guitar. That’s the thing with bluegrass – as long as everyone knows what key to play in, it’s not too hard to jam together. Finally a young lady stepped up to the mic and sang a song. She had a modern, almost falsetto style. I really liked the song she sang. Lots of talent at the Handlebar!

Today, I’m hoping Donna has her wheel dilemma solved and I can pick up her bike while I have the Jeep. Around 11am, I’ll start washing and waxing the rest of the coach. I’m waiting until late morning when the sun won’t be shining directly on the right side of the coach.

The RV park has a farewell dinner scheduled for 5pm tonight. Most of the snowbirds leave here by April 1st. The dinner and drinks are free! Never a dull moment!

 

 

Making a Plan

I won’t bore you with a weather report. Each day is pretty much the same. The only thing that varies is whether the wind picks up or not.

Yesterday, I started the wash/wax project on our coach. I washed the rear cap, then set up the Wen 10-inch waxer/polisher I bought from Amazon a couple of weeks ago.  It’s an orbital machine that came with two wax application bonnets and two buffing bonnets. Putting the bonnet over the pad is hardest part of using this machine – and that’s not too hard. It’s like putting a fitted sheet on a mattress.

I didn’t use wax. I used a polymer car polish. This polymer formula can be applied in direct sun with no problems. It protects the paint finish and contains UV inhibitors. This was my main goal. Our coach isn’t all that dirty, the paint has a nice shine. I want to keep it that way. The desert sun can really take a toll on the finish.

I spent about an hour, climbing up and down the  ladder applying the polish, then changing the bonnet and buffing it out. The orbital waxer/polisher was easy to use. I think I spent too much time changing the bonnet – I should have applied the polish to larger sections instead of doing a small area, then buffing it. It sure beats Mr. Miyagi’s (Karate Kid) “wax-on, wax-off” method.

I talked to our neighbor on the left side of our site. He and his wife are going 4-wheeling in the desert with their Jeep this morning. This gives me the perfect opportunity to wash and wax the driver’s side of the coach. Their Jeep is usually parked near the left side of our coach. I couldn’t wash the coach without getting spray (and leaving water spots) on their Jeep. I’m planning to wash and polish the entire left side this morning while they’re away.

After I put away the ladder and polisher, I went for a short mountain bike ride. Then I went to the pool. I wanted to soak in the Jacuzzi and then sit in the sun and read a book. I was enjoying the sun and book until a woman sat in the chair next to me. She started talking to me and kept asking me questions. I didn’t get it. If someone is sitting alone with their nose buried in a book, would you strike up conversation by asking them a bunch of questions?

I gave her a couple of short responses, then immediately went back to reading. She didn’t take the hint. I finally said, “Well, I’ve had all the sun I can take. Have a good day.” I came back to the coach and read for a while, then took a short nap.

I think we’ll move out of here in about three weeks. I’m getting the hitch itch and I’m looking forward to hitting the road again. Our plans are taking shape. We know we want to be in Great Falls, Montana by mid-June so Donna can race in the Senior Olympics qualifier. We want to be in western Washington by mid-July. We’ll be in Portland, Oregon the first 10 days of August. Then we’ll come back to San Diego around the middle of September.

In between those dates, we’ll see where the road takes us.

Chicken or Egg?

Yesterday was a fairly lazy day. I had a couple of chores to attend to, but nothing big. The night before, I sat in the Euro-recliner and felt it tilt to the side a bit. I thought one of the legs must be on the heater vent. I moved the chair and sat down. Crunch! One of the legs went askew. The bolt that holds the lower portion of the leg had backed out. The last few threads of the bolt stripped when I put my weight on the chair.

Stuff happens when your home frequently rolls down the road. Things like furniture are subjected to vibrations that they aren’t necessarily designed for. I went to Ace hardware and bought two replacement bolts – one for the repair and one to have as a spare. It was an easy fix.

After the chair fix, I read for a while. I went online and joined the Family Motor Coach Association (FMCA). I’m not sure if we’ll see much benefit from FMCA, but I joined in order to be eligible for the Alpine Coach Association (ACA). ACA is a chapter of FMCA – you must be a member of FMCA before you can join ACA.

ACA provides a lot of support for Alpine Coach owners. They schedule several rallies every year. We’re planning to sign up and attend the event in Portland, Oregon in August. It will be a good opportunity to meet other Alpine Coach owners and learn more about our coach.

After I showered, it was time to dump the tanks. I had the gray water valve closed over the weekend to build up some gray water. After I dump and flush the black water tank, I like to run gray water through the sewer hose. Soapy gray water is always my final flush. After I opened the door to the wet bay, my neighbor came over and started talking to me. I was sociable, but I really don’t like interruptions when I’m doing things like setting up, breaking camp or dumping tanks. So I stopped what I was doing and we talked for a while.

We talked about some of the other interesting people in the park. I found out that Forrest, the guy I helped retrieve a wrench from his engine compartment, isn’t 70 years old like I thought. He’s actually 87 years old! Donna and I talked about this once. What is it about the RV lifestyle? Do older people gravitate towards it? Or, does the relatively stress-free lifestyle contribute to long life? It’s one of those chicken or egg type questions that can’t be answered.

Around 4pm, I rode the scooter over to Lucky Lou’s. I saw the usual suspects out on the patio. I sat and ordered a Guinness stout in honor of St. Patrick’s day. I arranged to borrow Mike Hall’s Jeep on Wednesday to pick up Donna’s bike from the bike shop. I’ll also use it to go to the Handlebar Grill Wednesday evening to meet up with Andy King and enjoy some live bluegrass performances.

The people at the next table on the patio were obviously very intoxicated. I couldn’t handle how noisy and obnoxious they were. I guess I’m getting old. I finished my pint of Guinness and departed. I went to the Red, White and Brew Bar and Grill for a traditional St. Patrick’s day meal of corned beef and cabbage with potatoes and carrots.

The plate was good, but it doesn’t compare with Donna’s traditional St. Patrick’s day plate. Every year, Donna makes corned beef, cabbage, champ (Irish mashed potatoes blended with scallions) and Irish soda bread. She’s at her folks’ house near Albany, New York this week, so I settled for the plate on offer at the Brew. It’s the first time since I met Donna that I went out for St. Patrick’s day dinner.

Today, the temperature will reach about 80 degrees, as it has for the past several days. This morning I’ll start on the washing and waxing job. I’ll start by washing and waxing the rear cap. Once I see how that goes, I’ll decide on how to proceed.

Later, I’ll go for a bike ride, then hang out at the pool.

 

 

RV Mishaps

In yesterday’s post, I wrote about the RV mishaps that are posted on the RV forums and how I try to avoid them. I have a couple of examples of mishaps that I’d like to share.

Driving a large motorhome requires your full attention. When I worked for the Snohomish County Sheriff’s Office, we had mandatory driver training called the Emergency Vehicle Operator’s Course (EVOC). One of the lessons that was repeated many times in the EVOC training was to always back up your vehicle as if you’re about to hit something. What they meant was, if you have it in mind that you’re likely to back into an object, you probably never will.

Reversing a large motorhome can be challenging. But driving in reverse isn’t the only time you need to think about the rear of the coach. I posted before about swingout, but I’ll go over it again. The rear overhang of the coach causes swingout. For example, the distance from the rear axle to the back of our coach is 11 feet. If I make a sharp 90-degree turn to the right, the rear of the coach pivots around the rear axle. This causes the back of the coach, 11 feet behind the axle, to swing out to the left. It can swing out nearly three feet.

In the photo below, the driver pulled into a gas station. He then realized that he pulled up to the wrong pumps – there wasn’t a diesel pump in his lane. He carefully backed out of his lane. When he started forward, he cranked the steering wheel full lock to the right. What he didn’t notice was a pole at his left rear. The swingout of the rear end caused his coach to make contact with pole. The rear fiberglass cap was ripped away from the body. This happened in a matter of a couple seconds.

To add insult to injury, he then found out the station was out of diesel fuel!

I don’t have the full story behind the next photo. I don’t think the coach was driven into this position. It may have been a failure to set the parking brake, which allowed the coach to roll down the driveway, across the patio and drop into the yard.

Oops!

Oops!

They posted a video of the recovery of the coach on Facebook here. I’m guessing it was an expensive endeavor.

Yesterday I rode the scooter down to the NAPA auto parts store and bought six feet of 7/64″ rubber tubing to re-plumb our windshield washers. The nozzles for the windshield washers are located on the wiper arms on our coach. There’s a fitting where the wiper arm mounts to the body and another fitting at the nozzle where the blade mounts to the wiper arm.

The washer fluid flows from the fitting on the body through a rubber hose to the fitting at the nozzle, where it sprays the windshield. For some reason, the hoses on our coach came off of the lower fitting and shrunk. They wouldn’t reach the fitting anymore, so I couldn’t attach them.

I removed the old hoses and cut new tubing to the proper length. I put the tubing over the fitting at the wiper arm mount.

Then I threaded the hose through clips on the wiper arm and pushed the other end over the nozzle fitting.

It was a quick and easy repair. Before we leave Mesa, I’ll replace the wiper blades. I didn’t do it yesterday because I don’t see the point of putting new blades on just to have them cook in the sun while we’re stationary.

My next task will be washing and waxing the coach and cargo trailer. I know I said that last week, but I also said I would spend a few days thinking about it. After giving it some thought and reading how others wax their coaches, I decided to order a 10-inch 120-volt orbital waxer/polisher from Amazon. With my Amazon Prime account, it ships free and should be here tomorrow. I’ll let you know how that works out.

 

Forum Fighters

Sunday was fairly uneventful. Donna went for a bike ride and quickly realized that the race organizers had made the right decision to cancel the duathlon. As we feared, flood water had left sand and debris across the road in the low spots. Also, there were signs at the entrance to the park asking visitors to stay off the trails to give them a chance to dry out. While she was out, I started organizing the trailer and the main basement compartment.

I waited to load the scooter until we had the slides in and the jacks up yesterday. With the coach leveled on the jacks, the trailer was nose high. It’s hard to secure the scooter with the trailer at this attitude. The scooter rolls back away from the wheel chock while I’m trying to attach the tie-downs. With the jacks up and the air dumped from the suspension air bags, the trailer is slightly nose down. Then gravity works in my favor as the front wheel stays tight against the wheel chock and I can secure the tie-downs.

We fired up the engine around 10:30 a.m. While the engine was warming and the air bags were pumping up, I did a walk-around inspection before we drove off. We decided to take a different route back to Apache Wells RV Resort in Mesa. We left Fountain Hills and took a left on the Beeline Highway (Rt. 87). This took us east about 10 miles to the junction of the Bush Highway. We took the Bush Highway through the Tonto National Forest past Saguaro Lake and followed along the Salt River. We drove past our old camping area at the Phon D Sutton Recreation Area.

As were were cruising along, I remarked to Donna how much I enjoyed driving this coach. It’s so easy to drive, it rides smoothly and handles well. We have more than adequate power. On the RV forums I visit (check out my new Resources page), threads start from time to time regarding gas-powered motorhomes versus diesel. Just like threads asking which is the best oil or what are the best tires, people start defending their choices and it devolves into a forum fight.

I try to stay out of these types of threads, but I get sucked in on occasion. In the gas-versus-diesel argument, there’s no right or wrong. You choose what works for you. In the beginning, we chose a gas-powered rig. The purchase price was more affordable and I could do all of the maintenance work myself. We didn’t know at the time that we would be full-timing.

After living in it for five months and traveling 7,000+ miles, we found it didn’t really fit our needs. We wanted a different floor plan, one that was more open and conducive to setting up a work station. Although the big 8.1 liter (496 cu. in.) GM Vortec engine was powerful, we found ourselves struggling at times, especially at altitude crossing mountain ranges. I detailed some of the experience in this post.

I test drove several gasoline-powered motorhomes before we bought our first rig. Ours was built on a Workhorse chassis that had upgraded shock absorbers, a beefy rear track bar and a steer-safe steering damper added to it. It was the best handling rig of all the coaches I test-drove. But it was difficult to handle in windy conditions. Semi tractor-trailer rigs passing by would cause it to sway. Even with the suspension upgrades, the coach would roll and lean through turns. Coming down long, steep grades required good braking technique and concentration to avoid overheating the brakes. Was it a bad vehicle? No. Was it un-driveable? No. But it was exhausting at times. If we were weekend warriors, we might have kept that coach.

When we decided to look for a replacement, we set certain parameters. First of all, we wanted a rear-engine diesel pusher. We wanted certain considerations with regard to floor plan. We looked online and compared rigs for several weeks before we settled down to a few choices that met our requirements. Now that we own a diesel pusher, the higher purchase price, fuel costs and maintenance seem to be well worth it for us.

The big Cummins ISL diesel engine makes plenty of power. The engine also provides two stages of compression braking. I wrote about that in this post. The air-bag suspension rides smoothly and there’s very little body roll. For us, diesel is the right choice. I couldn’t go back to a gas engine, steel-spring chassis.

I guess I went off on this subject so I won’t have to jump into the fray on the RV forums!

We’re set up in a nice site at Apache Wells RV Resort. Our site has a large concrete pad. Donna directed me in as I backed the trailer onto the pad. Once I put the wheel on the front jack of the trailer, rolling it where I wanted it was a piece of cake. Then we positioned our coach next to the pad. We have our patio carpet out and chairs set up under the porch awning. The only downside to this site is spotty wifi. When we were here before, in site 56, we had a smaller concrete pad – the site was mostly gravel. However, we had great wifi there. There always seems to be some kind of trade-off.

By the time we were set up yesterday, we were starving. It was nearly 2pm and all I had to eat all day was a cup of yogurt and coffee. We hopped on the scooter and rode over to an old favorite, Senor Taco. I had rolled tacos with guacamole and Donna had fish tacos with a Corona beer. That hit the spot.

After we returned, I took a long, hot, luxurious shower. That’s the big plus of a place with full hook-ups. Unlimited water and sewer usage! Of course the trade-off is that we’re in a tight site with neighbors close to us and were not surrounded by nature. This will work for us until we get the hitch itch again.

Today I’ll catch up on laundry at the park laundromat. I also need to wash the scooter. Maybe we’ll lounge around the pool this afternoon. No real plan, just go with the flow!

Cooling Systems

Yesterday’s weather was fabulous. The temperature was in the mid-70s with mostly clear skies. Today looks like more of the same. This won’t be the case this weekend though. A large storm system is supposed to hit southern California tonight. In San Diego, they’re forecasting more than two inches of rain this weekend. This storm system should reach us by Saturday. We may have a wet weekend ahead.

Yesterday, after I posted, I went to work on my project of the day. It was a fairly simple task. I needed to adjust the v-belt that drives the A/C compressor. When I replaced the belt, it seemed tight. I knew it would loosen up after the engine was run for a while. The 25-mile drive from Mesa to McDowell Mountain Regional Park (MMRP) was enough to seat the belt.

When a new belt is first installed, it’s almost impossible to put enough tension on it to fully seat it in the groove of the pulley. You need to run the engine so the belt seats in, then adjust it again. I didn’t want to fire up our big diesel while we were at the Apache Wells RV Resort just so I could adjust the belt. I knew the short drive to MMRP would seat it in. Also, since it’s the drive belt for the air conditioner compressor and I wasn’t running the A/C, having a little slack in it wasn’t going to be a problem.

After I completed that task, I poked around the engine compartment. I was trying to figure out why some coolant was spit out of the overflow hose when I was parking our coach here. I brainstormed a bit the other day with my friend and former colleague, Keith Burk, and we came up with a couple of possible causes. Then I studied the cooling system on our Cummins ISL engine.

The cooling systems in these diesel pusher coaches are unique to each brand. When Cummins supplies the engine to the chassis builder, they specify certain cooling system requirements. The engine comes with the water pump and hose fittings in place. It’s up to the chassis manufacturer to provide a suitable radiator and plumbing for the cooling system.

Back to the problem at hand, it made sense to start with the easiest thing to check – pressure testing the radiator cap. The cooling system in a liquid-cooled internal combustion engine is held under pressure once the engine is running. The system is sealed. As the coolant starts to warm up, it begins to expand. With a sealed system, this expansion creates pressure. The radiator cap is designed to relieve the pressure at a specific point.

Having the coolant under pressure raises the boiling point. For each pound per square inch (PSI), the boiling point is raised three degrees Fahrenheit. In most systems, when the pressure exceeds the specified value, a valve in the cap opens and allows coolant to flow into an external, vented container. When the coolant cools, it contracts, creating vacuum in the system. Another valve in the cap allows the coolant to be drawn back from the external container into the system.

On our coach, there isn’t an external container. The Peak chassis utilizes a surge tank with enough volume to accommodate expansion of the coolant. The radiator cap is on the surge tank.

The other thoughts on why the cooling system overflowed weren’t so simple. One possibility would be a leaking exhaust gas recirculation (EGR) cooler. This would be bad, however, our Cummins ISL doesn’t have an EGR system. So that’s not an issue.

Another possibility would be a leaking head gasket. This also would be very bad news. I didn’t think this was happening because leaking head gaskets leave other tell-tale signs. I didn’t have any other symptoms.

My thought was to take the radiator cap into town and have it pressure tested at the auto parts store. Most auto parts stores will test them for free, and this was true at the O’Reilly Auto Parts in Fountain Hills.

I removed the cap and saw there was no need to test it. The seal was visibly bad. It was distorted and had ruptured. There’s no way it was holding pressure in the system. Although the fluid in the surge tank wasn’t boiling, this may not be true of hot spots in the engine. With no pressure in the system, the coolant will boil at about 223 degrees Fahrenheit. Parts of the cylinder liners and cylinder head may have had localized coolant boiling, pushing the coolant out of the cap seal.

My next task was to determine what pressure the system should be limited to. I searched online, posted questions on forums and went through my manuals. The only definitive specification I could find was in the Cummins engine manual. It specified seven PSI minimum pressure. That’s really low. Online I found anything from 10 PSI to 15 PSI. The old cap didn’t have a part number on it, but it was stamped with the number 14, leading me to believe it was probably rated at 14 PSI.

I didn’t want to over-pressurize the system and create a new problem. I found a 13 PSI cap that was dimensionally correct and bought it. Using the formula of a three degree rise in boiling point for every PSI, this would raise the boiling point by 39 degrees, making the coolant boiling point 262 degrees Fahrenheit instead of 223 degrees.

This is a long-winded, technical explanation for what amounted to unscrewing the old cap and screwing a new one on. If you’ve read this far, it must have some value though.

Today, I’ll head back to town to look for more effective allergy medicine. Donna is going for a run to test her new cooling system. She just picked up an Osprey Rev 1.5 Hydration Pack – a small backpack with a 1.5-liter water reservoir with a hose to sip from while she runs and rides her bike. She used to have a Camelback hydration pack, but the Dirty, Rotten Thieves got that when they stole our cargo trailer back in San Diego.

I also need to talk to Mike Hall this afternoon and see when he wants me to return his Jeep. It would be good if we had it on Sunday so I could pick up Donna and her bicycle after the race. On the other hand, the Jeep is open and if it rains on Saturday I don’t have a covered parking area for it at MMRP.
