Can my Dodge Durango GT haul a 4400 lbs travel trailer?

Chassis is plenty big, heavy and stout components. It will be safe. Better than the Toyota the other feller is asking about.
The V6 won’t win any races compared to the current crop of V8s but taker easy. It won’t like big grades, not for the weight but the wind resistance. 8speed ZF trans is a good crutch for lack of power though. Know what rpms is the the top of the powerband and choose your gear to max it out.
