2014 Dodge Durango w/Hemi (365 HP) and Passport 2650BH?

When I bough that same type trailer I was driving a 2004 Ford F-150 w/towing package (9000 lb towing capacity)iirc
I never had any issues and I live on the East Coast driving in the mountains.
Again I'm not the most educated on this but a tounge weight of
540lbs + truck cargo + family weight = Payload
That is the number you shouldn't exceed and quick look up shows your payload is 1330.
1330 - 540 = 790
Thats 790 lbs for your family, dogs and whatevere else you pack in your Durango.
