I tried that already. The employee (Jonathan D Sanders) agreed with me that real payload is calculated: GVWR minus curb weight; but stopped short of agreeing with me that real payload capacity is 1,700 lbs with the 5.7 (curb weight of 5,400 lbs)I am still curious why Dodge puts such low payload rating on the door sticker of the Tow N Go. 1200lbs seems way off. I have escalated the question with Dodge customer service and they should be getting back to me in the next few days.
He kept referring me to the 720 lb TW even though I never asked anything about towing.
Either way, GAWR will be your limiting factor towing a TT.
