I think a 2500HD/gas is adequate for most situations, we used one for several years for our previous 31' and a little later with the 34', that said, after a tour of the Rockies we opted for a 2500HD/diesel. There is an advantage in fuel mileage and a significant difference in comfort (the ability to keep up with traffic on the grades (any grade)) with the higher torque diesel. I really don't see any need to go to a duel rear wheel set up unless a fifth wheel with a higher load weight was towed, they are just too much to drag around the rest of the time. There is a significant cost difference for the diesel motor, but when we traded our last one the cost was recouped. Between last year and this, about 25000 miles with the 34', it is more comfortable to tow than the 31' after a slight adjustment for the additional weight. JMHO
