I would agree with Traveler II on good structural componants since you will be on the road a lot. Go for one rated for full time living like ours. We purchased a Heartland Bighorn in 2010 and it's sound, sturdy, and loaded with ammenities. We purchased one of their shortest models for versatility and glad that we did. It's just right for the two of us and recently took our son, daughter-in-law, and two granddaughters camping and we all slept in it comfortably. Well, at least for my son who slept on the floor on cushions but he said that was still better than a tent!
