Found my storage compartment was separating from the outside wall. Tried to tighten screws but no bite. Took screw out and found it mostly rusty. Wondering why it would rust when screwed into an outside wall. Is the wall leaking? Don't see anything open from underside.
We had the same problem with our last compartment drivers side. Found out it is a fairly common problem with the black compartments. Re caulked, held compartment to the side with large clamps then put a bunch of new screws in. Has held for 3 years now. There are post about the separation on here.
I think a Forest River rep stated the newer gray ones are more dimensionally stable when manufactured, so they have fewer fit problems than with the black ones. I don't remember if he said anything about any difference between them in strength.
Our 2011 Sunseeker has the black ones and I am thankful that I've had no problems. I did put some 2 x 4's between the floor of the rear compartment and the frame because it sagged. I wasn't worried about it failing but I was annoyed that the floor wasn't flat.

My 2801 separated in several placed. Had it fixed at a body shop under warranty. It almost looks like the compartment was molded too small for the coach. Even after being repaired, the compartment is very strained and bows in in between the screws, as if it is trying to pull away. This is, the grey one.
