We absolutely love our 2005 37B Itasca Suncruiser, putting 48K+ miles on it in 6 years. I think the floorplan your want has the kitchen on the street side with a mid door, correct? Ours has the two overstuffed chairs and workspace in the bedroom. In any case spending months on end is no problem at all. We've done 2 months out at least each of the past 4 years in the winter and I could stay out much longer, and maybe will some day.
Gary may have a point about the CCC on some chassis. If you're buying used (more than 2 years back) it'll be on a Workhorse Chassis, and if you can find one go for the W24 (24,000 lb. chassis) as mine has a CCC of 2,779 lbs. and a combined GCWR of 30,000 lbs. The W22, 22,000 chassis has less I believe. If you go new, the Ford F53 also can be had on a 24,000 chassis that would be worth the extra up-charge.
Ours gets 7.5 -8.0 mpg on average...which is about average for a gasser this size. Pulls a CRV like it isn't back there.
In any case we love the cabinetry, drivability and livability of this size and brand of gas coach.
Good luck with you search!
