I just picked up a 2001 2500HD 4x4 and got about 11 (haven't done the exact calculations yet) towing 5,000lbs from one end of PA to the other end of NY at 65 on cruise control. That was in Tow/Haul mode and it had to downshift a few times for some of the hills on 80, 81, and 84.
It is a lot better than the 8mpg (best ever) I was getting with my '87 GMC with the 454TBI/400 combo. I can't imagine how bad it would have been if I made this trip with it. I would have been stopping every hour to fill it!

This is from a post from tbyrne discussing Wester's tuning and how he reduces TM.
Torque management. Torque management ™ is GM's effort to reduce transmission wear by reducing engine output through timing retard during “abusive” maneuvers. The problem here is that GM believe acceleration from a stop is an “abusive” maneuver, as is punching the throttle during a highway merge. Both of these maneuvers cause an immediate reduction in engine power – the characteristic fraction-of-a-second delay you experience when you try to make your truck . We reduce this approximately 75-80%, which still leaves enough TM to protect from the most abusive maneuvers. We believe it makes for a safer and more responsive truck without introducing unnecessary wear on the drivetrain. The “Remove most all” option on the order form is appropriate for most owners.
