Donna and a few others beat me to the punch. I was going to say that FG trailers are one aspect of life where age really doesn't matter... much. It's already been said that these eggs age well, better than trailers assembled from flat panels, corner braces and what-all. The miracle of a trailer like my Scamp is that the body has only two pieces, three if you count the door. My whole trailer has no more than approx. two dozen moving parts, and most of those are cabinet hinges that don't move... much. Other moving parts like brakes
and wheel bearings are critical, but they're also simple to diagnose and repair.
Finally, old Scamps and Casitas look and live a lot like new ones. They're very established products, made by some very conservative companies. I don't think they spend a lot of R&D, and that's probably wise.
I used to live in Memphis myself, which was always a good place to get away from in the summertime. I imagine you're seeking one with air conditioning
. If you don't find it preinstalled, there are numerous approaches to adding one. When I take hot trips, I temporarily install a cheap window unit in my range cabinet, behind a set of louvers that used to ventilate a refrigerator
(now removed). A big roof fan will also do a lot to cool you down, but maybe not enough for your area.
Good luck and keep looking. The right trailer will turn up somewhere in the MidSouth region, if you're checking here every day, also on casitaclub.com,
