2010 Silverado 2500HD Fuel Economy - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I was wondering what everyone else is getting for average MPG on the Vortec 6.0 liter Stock.
I am getting 11.3-11.5 MPG from the computer.
I just refilled the tank and reset the OD to see what this tank gets me.

The truck is brand new with 500 miles on it. I have filled it up twice so far.
I need it to pull a 7000 lb tag a long travel trailer, so I went with the 2500HD.

Is this MPG normal? I guess I must have gas pump shock.... not used to this low MPG... My ole 87 chevy short bed had great milage even with 98,000 on it.

Any advice on increasing MPG without decreasing performance?
