Our 32' 5er is the longest we've had and we're in heaven but we don't FT in it. I've thought about FL but I'd rather not have to go up more steps every time I went to the living area. Another thought... I'd want a WD for FTing. I've seen 32'ers with a WD and I think it takes too much away from the rest of the space. I think it would take about 34'+ to have a WD so nothing else would be so squeezed together, just my opinion. 4 season construction, dual panes and 2 ACs if you plan on temp extremes. Solar (for dry storage) and/or generator and big tanks for dry camping. Large basement. Upgraded brakes, suspension and tires for safety, piece of mind and a good ride. Those are the biggies that I've already dealt with or will be dealing with on our next step up. Craig
