I have noticed rust on the screw heads in our trailer as well, but no other issues or problems with the unit. In fact, I believe they are well made. Ours has a problem with the molding because our dealer had to find a short, and while he put it back together pretty well, and did the silicon seal thing, you can still see that this was not the original work.

You may also wish to look at the frame to see if there is rust on them. Part of that will be result of road salt, and other things that occur for all of us. You can deal with most if not all of that with a wire brush and paint, which I just see as part of the maintenance of the unit.
