We don't fulltime but we have a 36 1/2 ft with three slides. The opposing front slides really open things up for a roomy feeling in a shorter rig. Part of my decision for shorter was campsite availability (especially holiday weekends in the northeast where I live), parking in my driveway and not wanting something too big for day or overnight trips. If fulltiming I would think what I have would be the minimum and would have no problem going larger. Layout and slides matter as much as length. I've been in some shorter rigs with full wall slides that felt enormous. Go to some RV shows and compare and see what feels right for you.
