Bob - congrats on the new TV! I also have 2 tows under my belt with the 2011 GMC (mine is a dually) after 8 years with a 2003 2500HD. The difference is amazing. Though my truck is 1400 lbs heavier than my old TV, the increased hp and torque blew me away. Towing is now much more enjoyable. And you are right, the exhaust brake is great.
