Your Durango will not be happy with that trailer behind it, and you won't be happy trying to drive it.
The trailer is too heavy and long for that vehicle. Crosswinds and passing semis--and yes, you will get passed by semis--will make it a white knuckle ride. Rough pavement will suck. If you have to make evasive maneuvers, you will have marginal control. It will be a white knuckle ride. Two lane roads will be only a little better than the interstate. Been there, done that, won't do it again.
SUVs are a compromise intended to mostly haul people around, maybe pull a boat to the lake on the weekend. A big, high sided TT with a heavy tongue is not within its capability.
