The floor of our largest storage compartment in our 2017 Four Winds 31W appears to have been damaged by water ingress over a period and has bowed slightly as a result. I cannot see any obvious places where this may have come from. The seal around the compartment door seems to be in good condition with no cracks or gaps. The underside of the floor also is fine and the protective coating is intact. There are no water lines or pipes anywhere close. So - asking if anybody in our community has experienced something similar and how it was resolved. Or any suggestions about how to protect the floor from any further penetration.
If that compartment is behind a wheel, driving in the rain will spray high velocity water against it, and under those circumstances it could be driven though a very small crack or ??? that would not be visible. I had a leak like that, right behind the left front wheel, on a former 41 foot DP, never could find the source in twelve years. I was careful what I stored in that compartment, knowing that things could get wet in there.
