Ok, just a quick update. The Expedition did a good job towing "the beast". Plenty of power and the Reese DC did a great job controlling sway on the trailer. I can see where the 119" wheelbase does come into play a little. A few time I could feel the back end of the TV wanting to dance around a little bit but not horribly.
However, three days after bringing the TT home my other car decided it wanted to finally quit working on me. Now I'm the proud owner of an '06 F-150. I think this will make a big difference. I still have to get that TV ready to pull the TT now, so unfortunately I cannot make a good comparison at this time.
As soon as the weather gets better I promise I'll post some pics of the TT and TT/TV setup.
Thanks again for everyone's replies.
