Thor 31F was our choice
We purchased our first RV in April, and we love the floor plan of the 31F. It has a LOT of light, due to what we call the picture windows. The bathroom, which includes the shower, is accessible (through sliding doors) from the bedroom as well as the main part of the RV. The kitchen area is a bit small, but has been fine so far, and we appreciate the way the dinette and sofa are laid out. This summer we took two short trips, from Jacksonville FL to St. Augustine and on to Disney Fort Wilderness in Orlando. We had four adults and two young children with us, and everyone slept comfortably. The cab over bed was a real hit with the kids, who made it their secret hideout when we were camping.
Overall, we love the design. Good luck with your choice!
