I dropped the camper back off Saturday to them and picked up the paperwork on it.
I left it at home, but I believe it said they bleached, washed, conditioned and sealed the roof and applied dicor where needed. It also said they applied some caulk on the front cap because it was starting to show age and crack.
I could see the new Dicor and caulk. Obviously the other stuff would be harder to see or verfiy. I was also wrong on the price. The $250 was for the labor, and another $60 in materials (which is what they quoted me originally).
Either way, it's now indoors for winter. I told them to pack the axles since it's now 3 years old. Campers happy and in good shape. Looks brand new still (no yellowing, scratches, torn anything, etc). We have been talking about a toy hauler, so it may get traded next year.
