We tow a similar weight TT with an '09 Silverado. Truck is CC, 4wd, 5.3, 6 sp., and 3.42 rear ratio. One thing I will stress is make sure you get the HD cooling package. It makes a difference in the ratings. Our truck handles our trailer very well. If you can find the max tow, get it, but it wouldn't be a deal breaker for me. I was looking for a max tow when I traded but only located one, it had high miles and a high price. They are rare both new and used. I looked at the ratings and decided we would be good without it.
