My folks had one similar to that in Florida. They made 3 models. One was a traveller, another vacationer, and another one. The lowest price one had wooden framing and the top one had aluminum framing. Theirs may have been a few years newer but looked similar. When they sold it the tires still had the little rubber tips all over and were so dry rotted they would not hold any air. Their biggest problem was roof water leaks.
