The main floor plywood seem dry and I haven't found any visible rot there yet.
There is also a separate plywood floor inside, under the bed/dinette seat. That turned out to be holding water from ?? ( the windows
maybe), and it had rotted out.
I've pulled all the windows
, and seen rot in some of the wood backing frames. I'm still thinking about what material to use for replacements. Cedar? It's not that expensive up here.

The part that is really susceptible to rot is the inside of the window frames. There is a plywood flange around the windows
. This is what the screws that hold the windows in bite into. They get exposed to moisture one way or another and rot. I would like to replace the wood in mine with something that does not rot. Aluminum? Duradeck? Nylon?
A 50 year trailer is my goal. I hope one of my kids wants it.
