Trouble with door, sagging wall

This is an old thread, and I did not realize I was a member here. 
I have the sagging wall issue with a 2013 181G.  In the process of repairing, I noticed a gap in the lower trim, and found I had water infiltration in the wall by the slide out. 
I also noticed the fiberglass buckled at the lower edge. Since I had the lower piece of trim removed, and had access to inside the wall, I found that the wall frame, which sits on top of the floor platform, had shifted laterally outward 1/4".  The wall is connected to the outer floor frame, by screws driven from below. In removing these screws, I found the ones by the shifted wall are broken off at the point where they meet.   I have no pressed the wall back in to alignment and fixed the delamination in the outer wall. The wall is no flat, the buckle at the bottom removed. 
I would say that one side of my trailer was held together by gravity and caulking. 

Checked axle and how it is connected to the frame.  No way to slide the axle side to side unless you or someone you know is good at welding.  Would require one to either remove and re-locate existing bracket on axle over a bit or simply weld another bracket on each end so the axle could be centered.

Boozer, has your fiberglass buckled too? Just think, if Forest River had issued a recall to add some $3 supports, I would not have had the fiberglass damage. Also, the repair shop said that because if the downward tension on the bottom trim, water seeped into the lower edge of the fiberglass.

Both sides of my 179 sagged. First the slide side and then the door side. The shop jacked up both sides and welded custom outrigger supports (6 on each side). Custom supports because Forest River was not responding with the part number for their supports. We wanted to fix it before we got more damage. The fiberglass had started buckling along the bottom trim piece.
