A 119" WB IMO is to short. I have seen too many SUV's flipped on their side towing 30' and larger RV's. They are not a good TV for longer RV's. Can they be made safe, yep. HD vehicle sway bars, e-rated tires and HD trailer sway control. But for the cost to do that, you can get a much better TV. Most crew cabs have a WB of 148" to 168" and are much better suited for towing a 30' and longer RV.
For the OP and his current TT any of the SUV's will tow it and tow it very well. If he knows that he is not going to upgrade his TT any time soon then go for it. Find one you like and if it's a Durango go with the 5.7 NOT the 4.7 you will be much happier with the Hime.
