David, it looks like you found a nice unit to start with, and did a great freshening up and decor coordination job.
The trailer was in pretty good shape frame and structure wise. Some serious mold/ mildew issues inside - some tilex and elbow grease took care of that. With the exception of the water tank, I had to replace the water system (lines, pump and faucet), put in new propane
regulator and lines, and am in the process of rewiring and replacing the converter and also adding battery
(with possible solar
upgrade this summer.)
The only major issue was some rot behind the belly band. The previous owner drilled through the molding cap and put screws in to tighten up the band - I don't think any caulking was used in the screw holes. I discarded the old belly band, cleaned out the rot and refiberglassed. I then put on new railing all around.
The rest has really been cosmetic - recovering the seats, painting
the cabinets and hanging blinds. Redoing the galley with stove cover, sink and counter top. New stripes on the outside with some fresh paint
on the frame with a little elbow grease to get rid of the oxidation on the fiberglass.
The next project is to add a rock guard to the front.
