Slide replacement

[Ogre]

After a 2 year covid hyetis, we hit the road again. We left Canada in hurry, trying to miss a storm front. Upon reaching southern Texas we opened the slides only to find out the main slide had leaked and has to be replaced. I have sourced new plywood, resin, and hardware.
What I can not source is the white plastic under slide cover. It looks to be. 090 " thick plastic. A local rv dealer is suggesting filon.
Is filon my only choice?

I think you can find something similar at a Home Depot/Lowes, if one near you.

I assume you are replacing the slide floor?

The white plastic on the outside underneath looks like nylon or some sort of poly plastic.

Yes I am replacing the slide floor. Both ends are rotted out. I tried to remove the white plastic, but it is original, and has become brittle. The top is the same material, except thinner.

Lowes carries 4' x 8' FRP panels .09 inches thick. (fiberglass reinforced panels)

While repairing your slide you might want to look into these to guard against having to do it again. You might be able to make your own.
