You say you suspect a window has been leaking not an unlikely, even so that needs to be checked and if so remedied before doing the floor, it might be the leak has just run down the inside of the wall in this case fix the leak properly and it should just dry out, but it might have leaked between the inner and out parts of the wall this is serious as it could track quite widely, as for the floor not seeing it is a real problem, could you take a picture from further away so we can see how large an area the problem covers.

I would think that the problem possibly extends to both sides of the van, but in any case you don't want a joint in the middle of where you walk, hopefully it's just on one side and can be sorted under one of the seats/sofas, the thickness and type of sheet you use is important if you want it to last you out or if its a fix and flog repair.

I might also suggest you get friendly with a decent joiner failing that maybe get one to come around and quote for the job and if expensive ask a lot of questions on method and materials.

Admin could change it not sure we can edit titles but a new thread called Rotten floor fix might get the attention it needs.
