The problem with this laminate techniques is that the fiberglass is laminated to some 1/8 ply which looks suspiciously like "luan" which is used on hollow core doors. Check the striker plates for the doors. My guess is that the adhesive in the luan is not water resistant and the plywood separates and swells up. Crappy any way you cut it. My brother has a trailer, 23LB, where a loose screw on the kitchen vent let in water and the wall bulged. He wants to switch to the aluminium panelled trailer which he feels is less prone to problems like this.
I have an issue with a loose screw on the molding at the back of the trailer just above the bumper. That will be the first order of business when I start camping again next week.
Does any know of a book or website that describes the construction of these laminated wall trailer and how to repair the bulges?????? It would be good if we could see some sections thru the various panels and joints to better understand them.
