It's OK to have too much truck, it is NOT going to be OK to have an undersize truck. I towed a 27' TT with a Toyota Tundra. It towed OK and I used it as a daily driver; I didn't know any better even though it was within it's limits. Once I got a Chevy 3500 and towed, I now know the difference for which some of us speak of-you won't go wrong getting a diesel. Overkill for your TT now, yes, but it will tow it so much better than a 1/2 ton daily driver. One other thing to consider, with a 1/2 ton truck; they size of the gas tank. Towing with my Tundra, I had to stop every 2 hours to fill up. That caused a big problem trying to find a gas station and was very inconvenient on a long trip.
