bed over cab floor replacement

[john68112]

I have a 1986 coachman classic. The plywood floor over the cab is bowing down at the edges. I have a water problem and have the problem with that fixed but now need to replace the plywood. Anything to get some insight into this project would be appreciated thanx...

I have a 1986 Ralley which had this same issue. The exterior is fiberglass so I removed the metal trim on the exterior around the cab over and remove the pieces from the front to the roof and between the cab and the cab over, after disassembling the trim and headliner. The sheetmetal of the cut out cab roof is screwed to the plywood you need to remove. The front window will need to be removed as well, if ther is damage to the front wall as there was in mine.
There is a square metal pipe frame on both sides and the plywood is screwed to this from the bottom. I used 3/4 inch tounge and groove plywood and new self tapping screws to replace the damaged wood. I also had to rebuild the front wall. I also had to replace the thin piece of leuwan which was covered with woodgrain vinyl which layed over the plywood decking as a finish piece. I used wood grained contact paper/shelf liner to cover a sheet of leuwan and it matched the wals enough you really can't tell. When you close up the exterior, get new buetyl tape to go under the metal trim. Hope this is of help, basically start taking everything apart in the area of damage and try to keep as much of the damaged wood together to use as a pattern to cut the new wood. Good luck
