Mark, what fun that big diesel must be! It's too bad that Hummer didn't stay around long enough for AMG to offer a diesel H2 - I think it would have been a big seller. A good friend has one of the new Chevy HDs with the diesel and allison, he tows a lot of horses in trailers and absolutely loves the diesel. Before he had a Ford HDF250 and averaged 6 mpg on his long tows, now he averages 13 with the same trailer and load. He also went through 2 transmissions on his Ford F250 because of all the shifting it kept doing in the hilly areas going back and forth from Missouri to Lexington, KY.
