I put a piece weatherstripping between the front roof edge and the top of the side wall, so when folded water can't get in.? The weatherstripping is stuck to the inside of the front roof edge.? You can't stick it to the wall because that would get in the way of raising the A wall.? The weatherstripping only goes from the front of the trailer to about 2/3rds of the way back, where the overlap with the rear roof begins.
But now when I setup the trailer, that new weatherstripping seals with the A wall, but it doesn't go to the peak.? So when water comes running down the bottom of the metal roof edge, some of it will splash above the seal, and wind up inside the trailer in the front corner.??
Just curious how other trailers solve this problem.
