I have a 2011 3500 ST CC DRW LB 4x4 with the 6.7L Cummins 6 SP auto and a 3.73 RE. No addons...strictly stock. I bought it used with about 36K on the meter. Mine averages 14 - 15 mpg not towing. I have only seen 19 mpg one time. I am an OMH so I generally do the speed limit. It has about 59K on the meter now and the mpg has improved very little.
