I recommend replacing sections perpendicular to the frame from one side to the other side starting from the back. The new section can be joined with a lap joint. I put two coats of resin on the road side and edges of the plywood facing the shell. I glue and screw the lap joint and screw the floor to the frame. The edges are glassed in with 2" or 3" wide glass tape to the shell. Just before putting the seats in I paint the floor with several coats of paint up to the glass tape. Send me a PM with your phone number and I will give you more tips on cutting out the old floor and pattern making if you like. Since you have a 79 Scamp
you should currently have a plywood floor.
I found your posting with helpful comments. You offered to another member with "Send me a PM with your phone number and I will give you more tips on cutting out the old floor and pattern making if you like." I would appreciate if you could look at my situation described below and offer any advice. I am a newbie so I hope I am following the proper protocol.
I just bought a Scamp 16, 2002 with floor rot in two places:
1. On the Driver side from the rear of the toilet holding tank drain for approx. 24" towards the back. From the shell edge towards the center for 6". The rot is over the gray water shower evacuation pump. Approx. 6"x24"
2. Immediately behind the Passenger side wheel well and back for approximately 28". From the shell edge towards the center for 10". Approx. 10"x28".
The rotten areas seem to be "rotten" in the sense that they have no glue, are loose wood particles. They don't seem to smell or have fungus/bacteria going on but maybe I am just not detecting that. One thought is to fix the source of water leak and leave loose material there, gluing or adding something underneath to seal the weak spot. Both areas are out of sight from inside the trailer unless you open up a door and look for them. The lower edge of the shell seems to have a trough or two horizontal lips of fiberglass which the floor board fits between, providing a little support of the floor. If you cut out a rotten rectangle piece and replace it with new plywood of some sort, what holds the new piece in place?
