Bigfoot 11.5 - take #2

So here goes my second time of owning a Bigfoot 11.5 -
We needed an off road capable RV with modern comforts that can haul a 18' trailer with 2 SxS's and do so on a budget.
We started with a Work & Play 38 5er and Dodge 3500 CC CTD- awesome hauler when in the desert but too big for the NW woods. Sold the W&P and got Bigfoot #1, an older 11.5. After getting it 90% done, someone made me an offer on the Dodge I could not pass up (it was a 5.9, 6spd, 4x4 CC), so it was sold. And with no truck, Bigfoot #1 was also sold after the rebuild and never getting used. Wife got a 13 Tundra, and while we did find TC's that would work, the idea of spending that kind of $ for something that will see woods use, just did not sit well. So we got an older Born Free and got it 90% redone - and actually used it this time. Did a good job of hauling but the E350 chassis was scary on logging roads and in the woods.
After lots of though and past experiance it was back to an older Bigfoot and a Crewcab 4x4.
And here the combo we started with:

Another lonely moss green 11.5 ignored in a backyard in the Portland area. It had some missing roof vents, dead fridge, and the typical old Bigfoot issues. But under all the moss and issues was a decent starting point, A/C, - had a title, and the price was right. After several hours to get it out of its hibernation spot; another done deal.
Truck is a 1990 Chevy V3500, Silverado, 7.4 TBI, th400, np205, 4x4 dually with a flatbed. All the power stuff worked, AC was cold, and over rather decent. Also included was a lift kit and sm465 conversion.

I really doubt you would need over 6 to 8 bolts.

Running up and back thru the mountains to Central OR we get 7-9 even while towing 5k. Out to the coast (still hilly) empty we got 9.5. We run at 55-63, as this has the aerodynamics of a fridge. Considering a stock p/u gets 10-12, this is decent for a 454 with a TH400 - non OD auto trans or lock up converter.

Thanks for the info on what is under the overhead floor, that really helps. I will tear into it this fall. Not sure mine has 5 strips, and has only 1/8 plywood.
As for the roof I had considered the inner rib route, but did not want to drill a bunch holes in the roof. However the inner rib is much easier than fiberglassing a bunch of ribs. And agree, do not want to pull the cabinets unless absolutely needed. I have access to a roller so creating the arch is not that big a deal. Another fall project..

The overhead is made up of the fiberglass, 5 wood strips (1" or 2" thk x about 2" wide) front to rear, and plywood (1/2" ?). I would consider replacing the 5 strips with plywood glued together, replacing the solid wood strips. I might even add a couple more strips. This link will give you an idea hof it is constructed: 1990 Bigfoot Rebuild

Although you have to look for the sag in mine, it is there. If it ever gets big enough for me to repair, I am thinking I will remove part of the ceiling paneling, and foam. Then I will run a piece of 1"x2" rectangular steel heavy wall tubing side to side. I might put one in front and behind the A/C. I would use shims between the tubing and fiberglass, to maintain the arc of the roof. I would use 3/16" or 1/4" carriage bolts with the head (easy to caulk) on the fiberglass side and the nuts inside the tubing. Obviously the tubing would have clearance holes for a socket to tighten the nuts. I do not think you would need to go inside the cabinets, just up to the face of them. The inside would receive a piece trim (2" to 4" wide) to cover the steel tubing.

Great setup. Excellent build quality.

I'm really digging the flatbed and extended hitch solutions... also the outside storage.

Take pictures of the work as you go... I'm betting lots of people are going to be interested in seeing the details.

After a bunch of trips and nights in it we have some updates issues to sort out:
Good:
Plenty of off hiway miles, smacked branches, ruts, washboard. - and it has not moved a bit on the flatbed. It is cool in the sun, and AC cools it off fast. No water leaks! Cool / warm / dry, comfy. So far one of the best Multi use RV's we have owned. Won't win any prizes at the camper show, but gets the job done.

Again, no broken fiberglass, but guess foam is delaminating from glass. It was sagging when I bought it, so off road travel was not the cause. Any fixes other than glassing some ribs onto the exterior of the roof?

Dang, turned out great so far. I bet it will get even better as time goes by.

I am impressed with your determination as well as your quality of work. As we have previously discussed, do not hesitate to question the mods I have made to my 1988 Bigfoot. There is really nothing I care to add, or redo (Wave3 install location excepted), on mine. As you know, I will not hesitate to explain why I choose the mods I have.

Been busy but here are progress some updates.

The side cargo area is all framed in, drop down doors frames fabricated and installed, stainless latches attached. The diamond plate skin did not arrive in time so had to run with out it for now. Before it first run in the mountains, stopped at Les Schwab Tire to have all the rubber valve stems replaced with metal, as they were slowly leaking.

The 7.4 moves the truck and the trailer loaded with the Can Am in mountains just fine. But the TH400 could sure use an extra gear between 2&3 along with an Overdrive. Even so it averaged 9mpg.


The LH side has room for all the camping stuff, chairs, BBQ, cooler fits in there as well.


RH side has a tool box built in, rack for the N2 tank, and room for all the pit boxes and spare parts.


Stopped outside of Sisters to camp. Hit several inches of snow going back over the pass the next morning - good thing for 4x4, it was a bit interesting...


It is a very comfortable and stable set up. So far no leaks, stayed warm overnight.
But do have a list of upgrades and fixes to do.

... I had the coil replaced in mine in 2005. I went with a local rebuild. It has worked without flow since then. I considered a new/newer fridge, but in talking to the guy, he suggested I stay with what I had. No $100 Dinosaur board to go bad, manual propane, 120v and 12v. Minimal things to go wrong and no parasitic load on the TC battery. I believe he was correct. The fridge is not automatic, and I know how to turn the knob on the controls.

Sorry, no photos.
Was able to get decent access to all the rear bulge areas with out gutting. RH side was easy, did have to remove the cabinet trim. The LH side was a pain, lots of contortions but was able to get new boards in there. Found out later with the water heater out is much simpler. Was able to replace 90% of the bad side wood. A prior owner installed aluminum plates and inner reinforcements for the rear jacks.
Agree with you on the older manual fridges; simple is always better, especially off road. After last weekends dead battery fiasco due to a portable cooler, decided to go with a manual one.

That is quite the tow hitch , how is attached to the frame ?


Rear hitch extensions are tied to the flat bed main rails (2x3x.188), and tuck under the truck frame rails. Nothing is welded to the truck frame rails - all connections to the truck are bolted. Here is a photo during mock up. This was the best option, as this truck had a service body at one time and the rear rails had been shortened.

Nice camper. I do like the fiberglass Bigfoots. Those would have been our first choice if we were not building. We have a fiberglass sailboat and love it.

... You are correct - the rear bulge was from the rusty screws pulling out of the 3/8 plywood they used as a backer when the two halves were screwed together. Cure was to pull out the bad plywood an used some quality 1x2 wood. Also used a few 1/4-20 bolts and big washers. Had to do this on both sides and the rear to Bigfoot #2 and #1. Wound up drilling new screw holes between the existing screws and new screws along the entire side. ...
