Will my 04 Ford Expy to TT i want?

I briefly used a 03 Navigator which is the half brother of the Expedition (w/ 5.4L 4v engine) and towed the slightly heavier trailer in my sig on short trips of 50 miles or less. I unloaded stuff from the front storage and even disconnected the front propane tanks and put them in the rear to keep the tongue weight at 900# so I wouldn't overloaded the troublesome and expensive air suspension. It handled it fine for those short and flatland trips.
