Hi, Beth.....
Welcome to the forum! You have many choices available, depending on the capacity of the SUV you have. For example, I've been happily towing a 17'
Casita Liberty (about 3300 lbs loaded for travel)....with a 2017 Hyundai Santa Fe V6, which has a 5000-lb tow rating.
Casita currently produces 16' and 17' molded fiberglass models.
Scamp makes 13', 16', and a 5th wheel....all in molded fiberglass. Always check the SUV's manufacturer tow ratings....and it's best to allow a 10-15% cushion on capacity over the trailer's
weight.
I suggest you look at the "Classified" on this forum, and on
Casita Club, and on Casita Forum. There are well loved and maintained used ones out there (mine came that way)....but they don't last long when posted!
Good luck....and I hope to meet you somewhere down the road.
Frank
