Well I took the corner off mine and that whole piece of wood is shot... Lookes like that corner of roof and floor too. Looks like the other corner floor has started too. Probably from the leak that was there ..
I barly managed to get the corner back on. I did reseal the corner with the putty but its only held inplace by the aluminum siding...
To me its not worth it to rip into it... What I plan on doing is tape some eternabond over the rubber roof that has the wood missing below it. Then get some liquid roof and coat the back last 1/4 of the roof to thicken the rubber...
I only paid 5 k for the camper.
Im sure if its osb under there it will just keep rotting wet or not...
Its cheap 1x3's in the wall..
To do it right I would have to gut the rear bath, remove rear siding and peel back roof. Way too much work...
