Question about towing capacity for a 2019 dodge Durango rt

When you say 5300# dry weight, is that including the brochure tongue weight? Both of those figure into the weight of the camper. Seems as though Gulf Stream doesn’t list Gross Weights.
After all is said and done, looks like you are out of payload for that camper and TV.
Do some more research to get a good idea of what your Durango can realistically tow.
Understanding all the weight ratings and what they mean will hopefully keep you from making an expensive mistake.
