Photos would be great. If I had to guess from the sounds of things so far, I'd say you'll probably end up replacing those front and rear flooring sections altogether. There are usually wooden cleats (like narrow shelves) running around the edge of the shell that the floor rests on at the edges. The general idea would probably be to cut plywood to fit, and then either impregnate it with epoxy resin, or use
fiberglass cloth and epoxy resin (depending on how far you want to take it), and then to "tab" the prepared new flooring to the shell as it rests on top of those cleats. To tab is to use narrow strips of
fiberglass cloth and resin to "glue" the flooring to the shell.
I know that there are quite a number of people who have made this fix to their Scamps, and there have been good photos detailing the process, so you might find some other threads by searching wherein you could follow along as those people went through their repair.
