Welcome to the forum. Looking at the Thor website, I see that there are some choices in that size and configuration. FourWinds/Chateau have a 24F and a 26B that have the rear slide that has the queen sized bed that is in the rear slide. In the Quantum line, the GR22 and the RS26 both have the bed in the rear slide. Best thing to do is to find a dealer that has the floor plan that you would like to see and go actually put yourself in the coach.
When we were looking, the rear bed in the smaller units than ours (28Z), looked promising, but upon actually sitting, laying and trying to imagine how we would use the coach, we found those previously "good" floorplans didn't work for us. IMHO nothing beats getting in the prospective unit.
Enjoy your search and check back and let us know what you find.
