I'd be looking for a 32-37 foot Carriage Cameo, NuWa Hitchhiker, or NuWa Discover America. I'd want one that had two ac's, and a heat pump, besides a normal propane furnace. I would also be looking for a rig that had at least 3 slides, one in the bedroom, and 2-3 for the living area. Just have 2-3 slides in the living area/lower level dramatically improves the spaciousness in the rig. Getting disc brakes, new/newer tires, black tank flush, and other options are also a potentially big bonus as well.
Second choice category would be a Jayco Designer or Montana, in the same length range, and options/features.
