09 F250 6.4L deleted and Spartan tuned. Unloaded I get about 13 around town and 15-16 on the road. Fully loaded this with the toy in the box and fuel this weekend weighing about 16k I got about 7.5 heading into the wind on the way there and close to 10 on the way back. I was running anywhere from 55-70. With the 3.55 gear set the truck really likes to run 65-70 and will maintain speed on most of the hills in central TX without kicking down a gear using cruise control.
