We had a 2006 Keystone Springdale 31 foot and towed it with a 3500 long bed crew cab duly Chevy Silverado gas pick-up. (Fiberglas body was breaking out), so got a new 3500 long bed crew cab duly Chevy Silverado DIESEL pick-up, and the difference was like night and day (same trailer). We now have a 35.5 foot Outback TT and the diesel duly 3500 tows ... truly ... like nothing is "back there", on flat land and mountains! It's a beast of a machine!
(my experiences .... are mine only!) Yours may be different, depending upon your state of mind!
