I've got an old (87) FWC Grandby with an aluminum frame and plywood bottom. Has worked for me. I lived for a while in a Skamper Travel Trailer. It did a fine job of keeping me warm or cool, depending on the season, and dry. I wouldn't shy away from a good wood framed camper, especially if your budget is less than you would like. Buying used, either construction type of any brand will probably have something that needs attention. With my FWC it was a leaky roof. My brothers Alaskan (wood framed), a bad seal at the roof/rear wall joint. You see Alaskans from the 60's for sale frequently in the NW that are still useable. As had been said, a lot of manufactures are out of business and budget, usage, sweat equity and truck fit should be your guide.
