See signature line, my TV is a Ford Expedition with the heavy duty tow package. The TT is 32' hitch to bumper. Sometimes I wish I had a 3/4 ton based GM Suburban or Yukon for the extra payload, but I just don't like them as well and everywhere I looked I could get more for my money with the Expedition. The 5.4 V8 has enough power for what I need, but certainly does not have the torque of a bigger V8 or of course a diesel. The 6 speed tranny and HD tow package with the 3.73 gearing makes this vehicle pull well and I do not regret my choice.
Watch closely what you buy, many SUVs or trucks may look the same, but are optioned out differently and towing ability varies a lot. Good luck with your search. BTW, when pulling my TT I get 9 - 11 MPG ... depending on the terrain.
