Opted for this truck with a V6 twin turbo engine. Has the same horsepower/torque as my 6.0 liter V8 in the 2500HD. It gets 16/22 gas mileage ratings. First tank got me 18.4. Used my dollars as a political statement on this one too. First Ford ever, and will likely never by GM again. Did not go for the politics and bankruptcy arrangement that Obama and GM collaborated on.
