Hi all, I've been lurking here for around a year or so. I have a 91 Warrior 321RB inherited from my grandfather a little over a year ago now. He purchased it almost new in '91 and kept it until last year before passing it to me. It's a good truck, immaculate with only 110k on the clock and a stack service records, with only a bit of rust around the hood hinges. The coach is in pretty great shape to be 31yr original, except for a few items I have been slowly working on (procrastinating).
The big ticket repair for my toyhome has been the cabover sleeper. At some point previously it has had some leaks, that were patched/covered. Well it turns out the damage had already been done, and the leaks also not fully patched. Not long after I got the truck home, I was inside cleaning it up in the cabover. Lo' and behold, the passenger front side of the cabover floor falls out from under me and I can see earth. Realizing I couldn't do much more damage myself, I began to pull everything out from that corner of the truck to attempt a repair.
Peeling back the layers, I discovered a current leak from the corner clearance light had been adding to the old leak damage. I pulled the clearance lights and replaced with new units and a good bit of sealant, no leaks so far. Luckily that is the only leak area I had found in the truck, it has sat thru many rainstorms since and is bone dry.
After getting the inside trim peeled back a decent amount I discovered the wood for the frame had rotted and many of the screws were rusted in half. Thus began the big project of attempting to rebuild the frame into working/better condition. I have minimal carpentry skills, I am an electrician so my experience with carpentry is limited to making holes in walls really; so I was going in a bit over my head with this repair.Armed with a diagnosis I headed off to Home Depot to get supplies. I picked up a decent amount of poplar wood boards to rebuild the frame, bcx plyboard for the floor, foam insulation, shower liner to retrim, and a hefty investment in stainless screws and PL adhesive.
After many months of procrastinating and doing little bits at a time, I managed to rebuild the cabover floor frame, attach it to the side and front walls, and deck it. I planned to keep the build as lightweight as I could, but I'm sure its a bit heavier than the original which I'de assume probably helps the truck balance out. I haven't taken it out on the road since, but I am confident in the strength of it as my daughter has claimed the cabover as hers and put it through the toddler test. It has survived thus far.
