I honestly dont know how people can say their 3/4 ton truck pulls a 15k fifth wheel just fine? I have a 2014 SRW 3500 and my trailer 13200 dry...as I said earlier completely weighed down for a long trip I was at the limits of 16500....yes it does tow it ok, but the more I tow in the mountains (I just got back from 570 miles in the mountains of west va, with quite a few miles off the interstate and "into" the mountains, and I recently did a 2700 mile trip from the east coast to the midwest and back, the more a DRW truck appears to be needed for additional stability and control.
My toy hauler puts my truck at 100% of its tow and hauling ratings (actually 100lbs over the rear axle and trucK GVWR of 12400)...and I honestly believe a DRW is needed...I cannot see how a 3/4 ton truck would be adequate for that kind of load (going off the camper GVWR here)? Lots of people seem to do it though.
