I bought this Warrior with the knowledge it had been setting for quite a while. What I didn't know was that the air conditioner seal had allowed water in at times.

The floor in the back bath is very spongy. My first thought was to remove the vinyl in the bath and replace the particle board with something. But looking under the rig the 1 1/2' box tubing they used to frame the floor with doesn't conform to any replacement pattern I can think of. I would have to add steel or rip out the shower and such-- which I would rather not do.

Has anybody out there removed the rotten particle board and floated the removed area with some type of resin or epoxy? There is sheet steel under it to serve as a form. Any comments or suggestions welcomed. Thanks

I have worked on trailers with such subflooring. You don't want to start taring up flooring. It would be easier to dry it up and add additional plywood underlay over the old. Screw and glue where you can and use heavy enough plywood to span soft spots.....

I've replaced flooring in my 1974 mobile home, and it is really not fun. Unless you absolutely must replace the particleboard (think hole in it), I'd recommend drying it out like homeless said, but I'd use an oil-based primer on it after its 100% dry. I had a water line in the front bathroom blowout last year, and the paint REALLY added firmness to the floor compared to before it got wet. Plus the primer will seal any mildew smells.

As a precaution, maybe use a thin sheet of fir over the primed wood. Its light weight compared to plywood. (Ply is stronger though.) Just my .02 cents worth.

Thanks for the comments and suggestions so far. I probably should say that the particle board underlayment was wet when I got the unit and has since been totally dried out and shrunkup in the process. That is where the problem lies--as it feels underfoot that the binder has been desolved and you are walking on woodchips.
