At first blush it seems doable but the key will be the Durango configuration. What engine, year, rear end gears do you have? The drivers door pillar will have a sticker indicating what load the tow vehicle can handle. Compare the cargo and passenger weights plus add trailer tongue weight of 700 lbs(12-15% of GVW) plus another 90 lbs for the hitch assembly to the sticker value.
Sounds like fun for your family but fuel economy and towing are mutually exclusive. Pulling a wind resistant wall through the air is the killer. Small engines and towing make mountain towing a challenge.
