I have a 1964 travco, 27 feet. I fell in love with her last year and purchased her with out knowing much about how to repair her. The front half had quite a bit of rotten wood. We cut out about 75% of her floor and replaced it with new plywood. It was a lot of work but doable. Travco's have a steel rib cage (reminds me of a whale) but wood around the windows, doors etc.
Check out my blog (especially earlier posts) for information on how we replaced the wood. This is a direct link to a posting on the floor install:

Ebay is a good place to look for manuals, brochures etc
We ordered new curved windshields that we will be getting installed this summer.
I have also collected a listing of other travco websites and blogs on my blog.
