All, first post here,
We just bought a 1987 25' Sovereign
that looked well maintained.
Wanted to go out camping right away but while cleaning under the left twin bed (the one on the city water attachment side) I notice the subfloor sagging by the rear end.
Upon removing the grey carpet I found that the floor (5/8" OSB, why not plywood?) had disintegrated in the last 4 inches around the curve, so I started digging more and I found a soft spot right in the middle, under where the nightstand usually seats.
I read about the issues with the bumper and I wanted to know if it's alright to just replace the damaged subfloor cutting to the first frame structural members available both transversal and longitudinal.
