I have an 06 2500hd 6.0 and a 2002 2500hd 6.0, the 02 avgs 11 mpg, and the 06 which i drive daily avgs 11-12 mpg, and I drive hard and fast, I have tried the whole old man driving before, and would avg 12-13 mpg.
I like the fact that I can get a loaded SLT GMC 2500, with the 6.0, for what a base diesel lists for. And can pull my fifth wheel, at under 10,000# empty, without breakng a sweat. This fall I will be driving my new 2500, coddled in heated leather bliss.
