Our custom true flatbed truck camper build thread

Ok, I am going to collect random thoughts and progress pictures and put them here in a thread.

Goal: Construct a true flatbed camper with cabover, no slideouts but full 8 foot floor width inside. This will mount on a 2006 Isuzu NRR truck with a GVWR of 19,500 pounds and a current dry weight of 8700 pounds. The truck has a 20 foot flatbed that is 8 feet wide. The camper will take up 11 feet of the flatbed and the remaining area will be home to a future garage for our toys. We will install a hitch so we can pull our 17 foot Montgomery sailboat (trailer + boat is about 2200 pounds). The camper and garage will be removeable so the flatbed can be used for other purposes, or in case the truck needs extensive shop repairs down the road. Or if we are in Alaska and want to go pick up 3 cords of firewood or something 🙂

Here is a picture of the truck with some important dimensions:

Amazing job! My brother out west is big into Adventure riding and has a couple GS's. Your rig look like something out of the Rawhyde Adventure group he rides with. Again, great job and amazing rig!

This is and has been one of my favorite threads to follow here. Sorry, Jfet you just can’t post enough pictures and info about your build and now, being used! Basecamping and exploring is not something that is frequently posted here, by others.

Right about this time in 2014, I found myself discovering the Mt St Helens area too. I fell in love with the area that my intended 2 nights extended into 3 weeks of hiking and motorcycle discover riding in and around the area, kayaking on the Cowlitz & Toutle Rivers. Proudly, all boondocking, which is my norm. Met some wonderful people who in turn welcomed me to visit, their large properties, to base camp to explore, all the way to the coast and Astoria. After that, kayaking on the Rogue River, for 5 days too.

About 290lbs each dry. We could put 3000 pounds in the garage pod and still not have a problem with the rear axle.

I wouldn't want a heavier bike but I have seen 400 to 500 pound BMW dual sports on single track. Not sure how they do it.

Jfet, as for Adventure Bikes, you are a bit off, they are around 700+ lbs. While the majority of riders never get them out of the urban areas and OHV areas, there are some of us that are quite adept and ride the single tracks, especially in Death Valley and Southern Utah. While I will pull out one of my two dirt bikes (CRFX 450 @ 261 lbs., 500 EXC @ 269 lbs.), my GSA certainly has the scratches, dents, caked on dirt and grime of daily off road riding. For me, there is nothing like riding one of the increasing numbers of Backcountry Discovery Routes on an Adventure Bike.

These Adventure Bikes, seem to take me to some of the most wonderful and beautiful locations. This is why I laugh, silently, when some scoff at my ability to reach such remote locations, but I do.




Climbing up into Death Valley on some of the back trails don’t slow some of the more experienced riders.




Some days the bike gets tired and picks a place to take a nap. Granted, a hazard of most off road riding, but a little more work when the bikes are laden with overnighting gear.




Then riding the trails along the San Juan River, running below Muley Point, drying out the boots is a day end necessity.




Hope to see some of you out on the road, during some of the best Truck Camper exploring season Labor Day through Memorial Day.

We took the camper to Mount St. Helens last week (first time ever visiting even though we have lived in WA state nearly 20 years).

We stayed at the Lower Falls campground on Lewis river. This is a great time of year to go as we had the entire campground to ourselves the first night. The falls are about a 2 minute walk from the camp site we chose.

We unloaded the motorcycles and rode them up FS road 25 then 90 to the Helens crater. This is a very good motorcycle ride and the day was a sunny 65 degrees.

On the way back from Helens we decided to take a detour to the WA coast since we were relatively close to Long Beach, WA. We ended up staying two nights on the beach at the Cape Disappointment state park and rode our motorcycles some 20 miles up the beach.

The camper/truck did quite well on the bumps (even got it on some dirt and gravel going to Lower Falls) and averaged 10mpg which made me pleased. The propane cage we added under the truck (holds three 20 pound cylinders) let us use the furnace and stove on this trip. We didn't run the furnace much because the camper seems to stay warm in this milder season (2 inches of wall insulation paying off).

Hi Wes,

You are only as old as you act. We were riding snowmobiles a few years ago deep in the mountains and came across a solo lady rider who was 78 years old on a 800cc Polaris mountain sled with a chainsaw strapped to the side!

I don't really have a go to forum for the WR250R but generally use Google search when I have a issue. I did solve the non-cranking problem we both had this summer. I replaced the fuel pump in each bike after mine quit on me again while getting ready to ride on the beach in Ocean Shores, WA 😞 A web search revealed this was/is a common problem but they changed the fuel pump design in 2014. I got the 2014+ model on Amazon for about $100 cheaper than a dealer and did the install myself (changed the spark plug while I had the fuel tank off since it is so hard to gain access). I still think it is a great bike...no other issues.

Thanks. Good info. Came within an inch of buying a 2008 WR a week ago. Wish I had acted sooner as they are a bit rare around here.

Jfet,

It's been a long time since I 1st posted. I greatly admire your project... I've long considered at least getting any TC again, but the youngster in me would still love to do it my way too. My budget is probably far less, and I imagine I am a bit over the hill, but it would still be interesting to see what could be accomplished anyway.

I also have developed a sweet spot for the WR250R's, as I can hardly kick my old Maico over anymore. What forum or other net info link have you found to be most helpful at knowing the little WR beast?

'Tis not over until it's over. 🙂

Hi Jfet - nice mod - are you installing some black plastic fenders and welding in a couple "blow out" bars over the drive wheels? The fenders self clean in snow and mud conditions if you mount them a bit floppy. A bit of lengthwise framework above the tires would protect your camper floor from an errant tire tread flapping around ... which of course would never happen once you used a good bike riding weekend to fabricate and protect your equipment...


Hey, thanks, I like that idea about the "blow out" bars over the drive wheels. I think I will do that next time the pods are off.

I hope to not have a blowout. We are not going to carry a spare tire because of weight and storage issues, so I am going to keep these new Toyo M608Z in the best shape possible. If we are so remote that we get a blowout and cannot get service, the plan is to unload the pods, swap a tire around (all six are the same) and drive to get a replacement. I am going to be vigilant about air pressure and inspection of tread/stuck rocks.

We have taken a few trips now and are still working a bit on inside cabinetry. We added a bag awning, welded up a propane cage that holds three 20 pound tanks under the flatbed and has a diamond plate aluminum front to match the other boxes, and welded up a really nice trailer hitch that bolts to the Mansfield bar.

This week we needed to take the truck in for regular service and decided to de-pod. While the pods were off of the truck, we removed all of the old wood flatbed, purchased three 20 foot lengths of new Apitong and mounted them. We covered them with 1/4" rubber screwed down and also fasted the same rubber to the top metal edge of the flatbed frame. The pods are now still well supported but we are ~600 pounds lighter. 600 pounds of junk, I mean cargo, we can add.

Had a night to sleep on it and decided we are going to just stick with our current battery system. It works great, is rock solid reliable, and probably will meet our needs. I get in a mode where I hate to see wasted solar power, but sun is a lot cheaper than lithium.

Another downside to the lithium I had forgotten about is they don't like colder temperatures and can't be stored below 0 degrees F. Might not be a great idea for the unheated garage pod.

On the motorcycle issue, we read that the vapor lock is a common problem with the WR250R in really hot weather and is likely what happened to us. The solution is to pour water on the fuel pump 😄

Our batteries on the motorcycles are brand new 2015, reading 12.8V resting voltage.
