Preventing Leaks - what would you do?

Please don't take this wrong, but for YOUR particular situation, you bought the wrong camper.

With this kind of health issue, you should have bought a camper with no wood.

BUT.. I have seen no reports of "regular" leak spots. Early models did have some problems with the rear window, so far as I know all covered under warranty. There have been some problems with window gaskets on a few trailers reported, and a couple claims of "upside down" windows.. seems impossible considering their shape..

The best answer will be to watch for it, and address any found as soon as spotted.

Also, if it was me, I would pull out all the upholstery, etc, open all the compartments, both storage, and "not" and seal every bit of wood I could get to with polycrylic or something. That would go a long ways towards preventing any mold issue that can't just be sprayed with some bleach solution and wiped down..

EDIT: I didn't mean to say run without upholstery.. was just thinking to point out to get into every space, seal every surface.. But (and what made me come back) Having the cushions and such recovered in vinyl or Naugahyde would make it easier to keep as clean as you need.. or even those fitted plastic gramma covers..
