I'm going through the same process (and I'm planning to visit an RV show here in September). One angle on this question that interests me is:
Are some types of RVs better for full-timing living in terms of durability? I've read some threads with comments that most RVs are not designed or warranted for full-time use. They are often built with materials that favor light weight over heavy duty. From what I've read I sense that Class A and Class C are sturdier and would hold up better to full-time use, but I don't know if that's true. Can someone address this idea? I would think the general ranking from best to worst full-time RV would be like this (which pretty much follows price):
Class A
Class C
Park model trailers
Fifth-wheel
Bumper-pull
Hybrid trailer
