Got some time to work on the camper last night, I need someone to look at this as I think the rot is going down the wall as well, if it is, is this worth rebuilding? I might be in over my head if I have to tear into the side walls, let me know what you think.
Picture of the rubber pulled back, rot galore.

Seeing rust on a screw right by the lift jack is scaring me, is this really bad?

Sorry for the bad pictures, it was getting dark. This is some shots of behind the housing for the stop lights:


Got some rot at the bottom
