New to RV's and just purchased a used 2011 FB21 Catalina from a dealer. Needless to say the piece of luan laid at the door did raise a question, but didn't find out till I was home that the floor just to the right of the door next to the bed was rotted through.
Have totally ripped back the linoleum, cut out rot, and reinforced with all new wood. I'm satisfied with the repair, but wonder where the water is coming from. It looked like it had been repaired before.
Insulation below the whole area was water soaked, but can't imagine water working up from below the trailer.
Looks like maybe water from around door but not sure. Under sash, or maybe gasket around door no good and running down to floor. Also, could it be the roof and running down wall to floor? Others have suggested leak through front storage pass through.
The rotted wood was just at the right corner of door when walking in. Didn't see any indication of water from further to the front or back of the camper.
Has anyone experienced a leak like this and able to help with an idea on what to caulk?
