Update: first tow with 2009 GMC 6.0
Hey guys, Updated the 2002 1500HD to a 2009 Sierra 2500HD 4x4 SLT a week ago. Got the new and improved GM 6.0 with 6 speed. Towed my normal camper down to St Pete for the week and wanted to report ...

I would trade up again, just to get the six speed transmission. I have had 2007, 2009, and now 2013 2500HD's and the biggest improvement was from the 07 (old style) to the 09, which got me the six speed. Lots of people report 10% better fuel mileage than I get. They might be using the computer? I don't.
