OK I bought this 5Th wheel under the impression it was in good shape. turns out i had several nasty leaks so i gutted it re did subfloor and walls put in laminate flooring but I'm still having problem with the wall in the bedroom area it has one of the windows that sits above your head and the pp that owed it before us ran screws through the cover for that window so now instaed of being able to just reseal that window I'm trying to figure out how i can just get rid of it any ideas.
