I had a 2016 Durango AWD Hemi R/T and Love, Love, Loved it. Purchased a Grand Design 2150 and all the specs were within the DD's limits (I later found out except 1. It was the Hitch Tongue Weight limit) It did pull it fine however.
Factory specs said 423lbs for the trailer. When I weighed the tongue it was 770lbs without any water. I found out later that was without batteries, propane, weight distribution hitch, and anything in the trailer.
Jeeps and Durango's have unibody construction and even though it has a class 4 hitch, it is only rated from the factory to carry 720lbs on the hitch "Period".
So my advice is check the tongue weight or like me you will be buying a different vehicle.
