I have a 3450RL almost fully loaded and love it other than a few problems I had with the refer and the bedroom air unit failing. If I had one thing that I would change, it would be to try to get the heat pump unit in the bedroom as well as the living space. The camper is spacious and hauls decently, though an F450 or better is really needed to haul it properly. I am looking for a medium duty F650 or so at the moment to haul it with. There is plenty of cabinet space and the full size shower is what really sold me on the unit. Overall I would recommend it to anyone especially full timers. My parents have a 36ft Wilderness that they full time in and absolutely love my 3450RL. (Get the air ride set up and the 6 point leveling system and you will not regret it).
P.S. I bought it to full time in also, though I have a few years yet before I can pull it off.
