Anyone have any hunches as to how this rot would occur? I bought this camper 4 years ago. It was one year old at that time. No issues that I was aware of, but didn't get an inspection. The steps ripped out on the left side last August, so took it to the dealer. The told me of the rot and said they welded some angle iron to the frame to mount it to. I see now that the screwed the angle iron to edge trim and this weekend, the far left side again, came loose. Obviously the rot goes further left then they thought.
I would check the calk on top of the door
Door caulking or a window next to it.
