What is the rated fuel economy for a 2005 2500hd crew cab with the duramax and allison combo. I cant find this info anywhere. I just bought this truck and would like to see how it compares to the factory specs.

the reason you can't find them is because they are not rated. The EPA doesn't do ratings for vehicles over a certain GVWR, I think its in the mid 8000 range so the 9200 GVWR 2500HD doesn't get rated.
