2012 Expedition EL w/HD tow package, longest travel trailer?

The other thing I didn't think about was that we will sometimes take my parents or her parents camping which would add an extra 325'ish lbs to the TV, we also have a kayak that we would take sometimes which would be another 100 lbs on top of the 325. So after all that the TV some times would weigh as much as 6800-6900 lbs (without tongue).
