My 6.4 with 4.10s usually got 13-14 mpg empty (2014 Ram 2500 crew long bed 4x4) and around 7mpg with my camper.
The Cummins is getting 18-19 empty and 11-12 with the little bit I towed the camper (but that was two fairly short trips).
The empty is mixed driving with a good portion on the freeway at 70-75 mph. It has dropped about a 1 mpg with winter blend fuel.
Those numbers are more inline with what I have seen in RL and on the other forums driving normal speeds. Don't get me wrong, I have seen a few 6.4L owners post 18 mpg from a trip where the wind was just right, but even they said it was not common. Someone quoting their best mpg they ever got when they usually get 2-3 mpg less under normal circumstances is very misleading.
