2003 Expedition and towing a new TT...thoughts?

I towed my TT which is 5500 pounds dry, 6500-7000 pounds loaded depending on the trip with a 2003 F-150 4WD 5.4L/3.73. It towed comfortably with adequate performance. Two gears to accelerate and one to cruise. 25 gallon tank at 6.5-8mpg meant 160-200 mile towing range.

Your TV is now 6 years older than when I bought my TT with that truck which only had 70k miles, shorter wheelbase, and I'll assume the same engine/gear. Change all the fluids. Get a good WDH with integrated sway control.
