South Cental Minnesota | I have a 2007 2500HD with the 6.0 engine and the 6 speed trans. I only have about 6000 miles on it but the mileage looks to be in the 11-13mpg. Poorer when it is cold out and a little better when it warms up outside. I can't say alot about reliability as it is near new but i'm sure someone else will answer that. I am hoping the mileage will improvw a little when I get some more miles on it. | |
