My previous truck was a 2005 F350, 6.0, super cab, dually Ford.

The mileage increase with the 6.7 2011, compared to 2005, was caused, in part, by the newer design of the 6.7 Ford engine and transmission, the 2011's increased torque, and by driving a little slower. The rear-end ratio is also different: the 2005 was 4:10 and I think the 2011 is 3:73.

However, the 2011 DRV is slightly heavier than the 2005 DRV, which could influence lower miles per gallon. We also try to keep the "stuff" we take with us under control to keep weight down.

If you want more exact miles per gallon info, I can give you the exact miles per gallon on each of the trips with the previous equipment (2005). However, I haven't done many trips yet with the 2011 equipment so the mpg history is a bit thin. I will pass it on, however, if it might be helpful.

The 6.7's towing capacity is noticeably higher than my former truck, the 2005 6.0. The higher towing capacity of the 2011 is roughly 5,000 more lbs. than the capacity of the 2005.
