The Adventure in Backpack:

As our followers know, we are downsizing our lives once again which means we are selling Backpack, our house on wheels. It has served us very well for the last 8 months and we are honestly a bit sad seeing it go. If you are reading this ad here on our blog, you are a friend and we want to be able to give you as much information about this RV as possible because, honestly, our goal is for one of YOU, our friends, family, or followers to purchase this RV and go have an adventure all of your own! We will be posting this on a few different sale sites, but this seems like the most personal way to get this out there to our friends who are actually been seeing where ‘Backpack’ has been taking us.

Here is the no-holds-barred story of the RV (with associated pros and cons) over the last 8 months. December 2015: Purchased the RV from Transwest Truck and Trailer north of Denver, CO. It was a single owner RV from a fella’ out of New Mexico. When we bought it, the RV had 12,000 miles on it and the generator had 150 hrs on it. We were warned about the fact that it only had 12,000 miles over the last 7 years as that meant it sat around a lot. On the flip side, this also means that the engine wasn’t even broken in yet. When we took possession of the RV, we installed a Dickinson p12000 propane heater in the bedroom and a composting toilet in preparation of spending the rest of the winter in Kremmling Colorado in sub-freezing temperatures. The supplemental heater SAVED us SO much propane over the course of the winter (Oh, the RV has dual pane windows too). The composting toilet was awesome for that winter camping in the fact that we did not have water on board during that time as to not damage our pipes.

In April, we left Kremmling on our epic road trip. We headed west. We were incredibly happy at how the RV handled the passes on I-70 in colorado. We were going about 35mph on the way up the passes, but that’s the same speed the big-rigs go, so as we would learn, the ‘truck’ speed limit is the one we should go by anyway. Descending the pass was a breeze as well. The Allison Transmission coupled with the Engine Brake made it so I rarely had to touch the brake pedal.

Once we got into Grand Junction, we lost engine power. We found a parking spot at a Napa auto parts and started self trouble shooting. The cool thing about a 2008 motorhome is that there is a near infinite amount of information on the internet from people who may have already had the problem with an associated fix. We changed the fuel filter and the air filter ourselves and that did not fix the problem. We were at a loss so we limped it over to the local Transwest and had them take a look at it. After 2hrs in the shop, we had power again. A hose clamp between the turbo and the intake manifold had come loose and the hose boot was plugging up the intake tube. A new hose clamp and boot and we were good as gold again.
Through Utah we encountered some really steep and windy roads with grades up to 14%. Again, the 330 Cummins ate those hills for lunch.
We eventually made our way to Montana where we installed our solar panel setup. We installed 4x160w solar panels to 6x6v golf cart batteries for 660 amp hours. We also installed a 2800 watt magnum inverter. These are all top of the line components ($$$$$).

On our way to Montana, we started having a problem with the alternator overcharging while it was raining. Basically, the voltage regulator was shorting out and pushing out 17v. We ordered a new alternator, installed it ourselves, and the problem was solved. The overcharge tripped a safety in one of the slides and caused it to ‘forget’ the settings where the slide starts and stops. After some troubleshooting and some phone calls, we were able to do a field reset on the controller and we were good to go again.

If you aren’t picking up on this… there WILL be things go wrong, but with a positive attitude and a bit of problem solving, you can solve most of the problems without taking it into the shop.

On the drive across Canada to Alaska the RV tracked straight as an arrow and soaked up all the associated frost heaves that were thrown our way. The RV was unable to dodge a rock from a dump truck though… A large rock smashed into the drivers side windshield and broke it. It was out of our line of site so we opted to wait until we were back into the lower 48 to fix it. Note: if you go to Alaska, get glass insurance, this is apparently a common problem and if you make it to Alaska and back without a broken windshield, you are very, very lucky.

Once in Alaska, we traveled to Fairbanks, Denali, and down to the Kenai Pennisula enjoying all of the BEAUTIFUL scenery. Near Seward, we had another loss of power. We replaced the fuel filter in a roadside turnout (replacing the fuel filter takes less than 30 minutes) and the problem was solved. (we have learned that if there is something wrong with a diesel engine, changing the fuel filter will generally fix it…apparently…)

Upon leaving Seward we headed back toward the AlCan Highway. We had no issues across Canada even on a super windy (and incredibly scenic) stretch of road the goes north to south straight through British Columbia). By the way, the brakes on this RV can stop on a dime when a black bear decides to run out in front of you…be sure to secure all of your things inside the cabin! North of Whistler BC we encountered the steepest road yet. The ‘truck’ speed limit down this cliff hillside was 6mph and had 2-3 hairpin turns. I put the Allison transmission in 1st gear with the engine brake on and crawled down the hill. I never felt the slightest bit out of control. Good stuff! Going up the 13% grade on the backside of that mountain was slow going, but the RV never struggled. There is a reason that they put this motor/transmission combo in semis.
Since then, we have not had any challenges or issues with the RV.  We would like to think that the frequency of those minor problems we were having were due to the fact that the RV had not been used very much.  The frequency of the problems has decreased dramatically since we have been putting miles on it.
We hope that we have inspired you to take adventures, and this RV is an awesome opportunity for you to start up your own RV Adventure. This RV is pretty much perfect for that cross country road trip or heading to Quartzsite, Arizona for winter to avoid the cold (you’ll love the solar, the composting toilet, and the supplemental bedroom heater if you do this.  Honestly, that’s where we would have been heading if we were not selling this).

If you are interested in purchasing this RV so we can all start our next adventures, e-mail me at so we can schedule a showing. We are currently in Blanchard, Oklahoma, and will be here until the RV sells. If you need to travel to see it, also let us know so we can arrange logistics. If you live elsewhere in the country and DO want to buy it from us, we can arrange delivery if you need it.


Without further delay, IT’S PICTURE TIME!!
