We found a '79 Trillium Jubilee in need of some tlc. All original, the wood cabinets/doors need refinishing etc... we intend to spend a year on it, taking it out next summer. Great site here!...very helpful community. glad I found it.
My suggestion is to clean it up go camping this summer and see what you like and don't like about the camper the way it is now and then in the Fall and over the winter if you have a shop or heated garage make all the changes and mods you need so it will be ready to go out again next summer.
