OK - so in this thread the OP acknowledgesthat they will not be upgrading the TT, so on the lines of Mike Up's advice, I searched on CarMax.com at the San Gabriel Valley/Duarte location. They have a
2012 Ford F150 XLT 4D Crew Cab with a GVWR of 7350-lb and a Payload Capacity: 1700 lbs. I don't see why this could not work for you.
Do yourself a favor and don't have a knee jerk reaction and fly out the door to buy a TV. Don't limit yourself to one brand just becaues everyone else has one. Take your time, research at Carmax and AutoTrader.com and your local CL ads. Call up dealers and tell them what you want. GO SLOW. Otherwise, you will have spent a lot of money and be unhappy.
