We towed a 31 foot Mallard TT packed heavy with a 1/2 ton dodge passenger van , 318 v8, WDH, and sway bar. Slow and steady up hills and watched our gauges. No problem. Finally upgraded to a 3/4 ton dodge van. 383 v8 that sucked the gas like it was water! But it didn't tow any better! Give your rig a try. Take it easy. Tow without water tanks full and watch what your van does. It Will tell you if it is straining. Good luck.
