Does anyone have any fuel mileage information on the new 07 trucks with the duramax? I'm curious if they are getting as good of mileage with all that new emissions BS......

according to the guys on dieselplace.com, the numbers are all over the place. a lot of guys are getting an average anywhere from 16-21.

A buddy of mine has a new LMM and he won't say the mileage. He had a Dodge and claimed 20+ but he hasn't said on this truck. I do know that he had to fill up twice to get 350 pulling a 8K trailer. And died twice going down the interstate at 70 mph. But it hasn't done it again so he prolly got in some bad fuel.
