My BC is at the dealer right now for the same problem (so far 1 month). I stopped by to check out the progress and was told that Heartland is making a new front wall (including overhang) for me. I got to look at that piece that was removed, and was surprised as to the actual construction of the wall. It seems that the laminate is attached to a layer of, for no other words, cardboard! The side walls are on 1/4" luan like boarding, but that front wall and overhang is in essence cardboard. Cause....cut too small at the factory, the horizontal seam where the overhang and side walls come together was not done well, and in some places not sealed at all. This allowed the water to drain down the side walls and seep into the overhang. No where to go then until you upset the level of the unit. Jack the front up and out it comes. I had already started to de-laminate below the front storage door. Luckily the side walls hadn't started to absorb moisture to start what would have been really bad.
