I had an 07.5 Long Bed Extended Cab 2WD Silverado Allison Duramax with the LMM engine (no urea) and I consistentently got 13.8mpg pulling an 8285 WS Rockwood Signature Ultra Lite 5th wheel. Unloaded on the highway it was 21-22 mpg but I seldom went above 60 pulling and 65 empty

Although it's a 3500 dually, I have a RAM with Cummins, Aisin tranny, 4x4 crew cab, long bed and it gets between 9.5 and 11 mpg depending on the topography towing a 16,300lb 5er, and 17-18 unloaded.

2006 lly Duramax with Allison crew cab dually 4x4. I'm about 18,000 lbs fully loaded and get about 7 mpg with the cruise set at 74 mph. I get abut 9.5 mpg at 60 mph. No load around town is 16.5 mpg and no load interstate is 19 mpg. No load, 55mph, 21.5 mpg. It's chipped, but the tune I use is dependent on if I'm loaded it not.

Not me, the truck. If I'm loaded, I don't drive.
