That truck must have spent some time idling. I'm a flat lander.
I get 7-9 mpg when towing (37.5' 5er - about 12,000#), 12 city, 15 mixed, and 17 - 18 mpg hwy with mine.
I have a videos posted that show the EVIC. ~7 mpg when pulling a friends 41' 5er that weighed in at 14,000#, and the 17-18 mpg hwy. These are no BS numbers.
My 5.9L Cummins with 3.73s got about 2 mpg better across the board.
If I remember correctly you have 4.10's?
If I could get 15mpg empty avg and ~10mpg towing my 25' 7600lb(wet) travel trailer I would be good with that....exactly what I currently get with the Tundra.
