I'm interested in the model above but my tow vehicle is a Dodge Durango 4x4 5.9 rated for 7400 lbs towing. The gvwr for this trailer is 7640. Would I be able to tow this as long as I don't fill the fluids such as water, gray water and sewage to capacity. I would not be hauling it with anything in the holding tank. It would be used for weekend camping, no cross country stuff.
