    Welcome to the Site!

    2011 Silverado with a 6.2, is that the 1500 trailer max? So all I can comment on is what I have read about the 1500 on line! You will probably see the same Mileage as us with the 2500HD. I think i remember seeing 10mpg in the city and 14 on the hwy

    I dont know if its fact or myth that an SUV will get better milage due to Aerodynamics or lack of drag due to no tailgate however that mileage sounds terrible.
    The 6.0 in my suburban 2500 will get no worse than 13.8 in town and at least 18-19.5 mpg on areg. basis and thats with a Tire size larger than offered on the 2500 suburban, But i do drive like an adult and dont bury the gas pedal.

    My 04 2500HD 6.0 gets about 11.5MPG around town.
    We had about 3" of snow last week so I stuck it in 4WD. 9.3MPG over about 120 miles of mostly in town driving.

    Does the Suburban also have the 4.10 rear end? A lower ratio may give you much better mileage. Like Jake, I bought the 2500HD mainly for towing 10,000# trailer. Fortunately, I work only 2.7mi from home, so city MPG isn't a huge deal. I can't wait to see the MPG when towing :(

    How does the MPG on the turbo diesel compare? I am under the impression that it's best suited if you are towing most of the time with the truck, since the diesel towing MPG is better than gas towing MPG. Even with the higher cost of Diesel.
