Theresa,
I picked up a 86 Serro Scotty last summer. It's in good shape so no major work needed except for the roof. NSSO recommended one restorer in Pa, Tom Bernot. I dropped off my Scotty after Easter and I'm in line(two trailers are ahead of me) for a total new roof.
You can see some of Tom's work on the NSSO site. Instead of a rubber roof he's going to use aluminum. The 3 way fridge was long gone but Tom will be removing the roof vent for it and I'm putting in an extra roof vent. So there will be two vents with two Max air covers.
Once I get it back I can continue to personalize it, including trying to figure a good a/c option. But the biggest reason to buy this was a bunk space for my nieces and nephews and a camper for fall and spring. I use the teardrop mostly in the summer.
The cushions are in good shape but I'm replacing the foam inside. I'll use throws for the cushions like the picture shows because I'll be traveling with my dog. In the kitchen I already made a new cover for the stove top and sink top to increase counter space. So just like a td I think you are never really quite done!
Good luck on your project and would love to see your progress on your Scotty.
