My New Ram 2500 6.4 MPG Update
Posting this because people ask about the mileage: First 300 miles: 12.2 mpg mixed driving. 2 days were in below zero weather and gas had 10% alcohol mixture.

Thanks for the follow up. I suppose the cylinder deactivation on this 6.4 engine only activates at highway speeds and that maybe where the improved fuel economy over the 5.7 hemi will come into play.
