2014 Dodge Durango Towing abilities

I need help figuring out if a 2014 RWD Dodge Durango Limited (or R/T) 5.7L V8 Hemi with a tow package (rated to tow 7400 pounds) can tow a Lance 2285 27' trailer (or equivalent). Trailer dry weight is 4150 pounds (add to that a couple hundred for options) - GVWR is 6000 pounds. The kicker is....some times I will have 4 adults and 2 kids in the Durango -- total passenger weight around 750 pounds. I've been told by the LANCE and the Dodge Dealer that I should not have a problem. But I would love to hear from anyone who isn't trying to sell me something. At this point I'm wide open. I LOVE the Durango - I could (but I don't want to) get a smaller trailer OR I could (but don't want to) get a full size SUV (Tahoe/Yukon/Expedition). :) But if there is concern AT ALL with the ability of the Durango to tow a 6000 pound trailer with 6 passengers -- I will explore other options. I live in Colorado and will be heading over the Rockies. I need to be confident in my tow vehicle. Thanks all!
