Duramax L5P Fuel Mileage
Anyone have any real world experience with the fuel economy of the new GM L5P Duramax in a 3500 DRW?

A bit of a hijack here, but this MPG talk reminds me of a summer job I had in the mid '70s carrying drywall (what a way to make a living). There was a regular run out to one of Calgary's bedroom communities, about 20 miles, mostly highway. There was a gooseneck loaded with drywall, pulled by a Chevy 2500 454. We got between 2 & 3 MPG. How things have changed!
