Floor Repair

First you have to fix the source of water damage, otherwise, fixing it is not going to be worth your time.

The "subfloor" is a multi-layered/compressed/glued concoction of thin plywood (1/8"?) on interior (under vinyl flooring), exterior layer also being the same plywood with under belly material coating. Sandwiched between these layers is a 1 1/2" welded aluminum frame. Between the framing members are large pieces of foam that are cut to size. all these pieces are put together, glued and "pinch rolled" under 1600lb psi. The floor in an R-pod extends to the outside edge of the walls, meaning they provide wall support, also meaning they can be a real pain to work on.

What thickness is the subfloor supposed to be?My Rpod 176 is shot in the back of the bed area below the back window.Never done this before nor am I am experienced carpenter by no means.Thanks for you input.

Id still suggest adding the outriggers under there, the wall loads need to be carried back to the frame rails, and half inch of plywood and a few thin pieces of floor metal wont do that. It's not the weight of a couple of people, it's the loads (and 2 plus g's bump loads) from the entire wall and roof structures and everything attached to them.

I agree with you about the rpod throw away design. Cheap and light but not something anyone should expect to last very long. One reason I sold mine since I wasnt expecting to be able to use it for a few years. I'd rather just get another trailer when I need one again rather than try to maintain one in storage for several years in a humid environment.
