Had an MRI on my left shoulder a few days ago. Haven't heard back yet on what I did to it, but it's feeling well enough to continue working on this. I'll keep chipping away at it as long as I can.
I put the edge trim back on the driver-side last weekend. Had to spend a good while cleaning all the old goop off of it first. Then put new putty tape on the inside surface, and hung it in place using the two tie down eye-bolts that go through it. Then working from the front corner, I used a 2x6 board and the camper jacks to press the trim into place and squeeze the putty tape flat. I'd raise the camper, place the board where i wanted it, lower the camper against the board and let it sit for a few minutes while I put a screw in. Then raise the camper, move the board 6" or so toward the rear and do it all over again.

Now it looks like this:

This area where the trim goes down the front edge of the skirt was the hardest. Had to get out my long pipe clamps to squeeze the trim into place here.

I also found a source for some stick-on molding to cover the seam on each side. A place called
Brandsport has the flat trim in several widths and colors. I ordered a couple of color sample cards from them off their website (free) and there are 3-4 that will work fine. I can either go with a cream/off-white color like what was on there, or try a color that is close the the colors used in the decals on the camper. Haven't decided yet, but I'll be ordering some soon. I'll probably use 2" wide molding rather than the OEM 1.5" so I don't have to do something strange looking to cover the stepped cut on the driver side skirt.
Now I've moved to the passenger side and have removed the vinyl covering from the lauan plywood covering the wing and tub area using a heat gun. It came off pretty easily. The wood is in good shape on this side. That white area around the 110v outlet and the fridge drain is from an earlier repair. The fridge drain wasn't installed correctly and was causing water to get inside the structure and rot the plywood.

I guess just for consistency I'll put some spar-urethane on the wood before I put the FRP on it.
More later...........
