Welcome, Renee!
You may find the
Casita rather boring after your restoration projects. As long as the previous owner(s) kept up with basic maintenance, they just keep going and going and going. You’ll have to content yourself with small cosmetic and functional upgrades.
But seriously, molded
fiberglass is a great choice, and the
Casita 17 is the top-selling model. One specific issue to watch for is softness in the floor. Casita has a sandwich floor: plywood between two layers of
fiberglass. It generally resists water penetration, but if a leak does find its way in through a crack, screw hole, or plumbing cut, and the source isn’t promptly corrected, the plywood can rot. It presents as sponginess when you walk on it. Repair is a messy project you are perhaps looking to avoid this round.
We’d enjoy photos of your previous projects if you care to share. I’ve always had a soft spot for those Apache folding trailers. Saw quite a few in campgrounds as a kid growing up in the 70’s.
Best wishes in your search!
