There is a bent angle plate at the very rear of my trailer; it's bolted between the rear frame cross member and the plywood floor, and then bends up to follow the rear of the trailer; it is riveted to the C channel, but not to the skin, interestingly enough.
On my trailer, the rear storage compartment top is hinged to a sheet of aluminum, which anchored just underneath the hold down plate and on top of the frame. This design leads water directly to the frame & plywood... and everything starts rusting, corroding and rotting...
I replaced the rear hold down plate with one bent from .060 304 stainless, and riveted the plate to the skin as well. I omitted the hinge mounting sheet entirely, and am placing an heavy aluminum angle between the frame rails to support the top of the storage compartment. Water is going to enter that compartment; I'd rather not have the water end up under the floor of the trailer...
