The one truck outdoing me is a 2019 midroof cascadia with all super singles and the dd15 with dt12 automated Detroit trans. Other's behind me are couple Coronado's, t800, another t680, dad's 579, and assortment of w9s,379s,389s.

I pull a van and I'm lucky to average over 6.8 mpg. The wind has the biggest effect on my fuel mileage, more than weight of load and terrain, Lately I've been getting much better but I pull an empty container (8000 lbs approx) one way 200 miles, and then a loaded container (12000 lbs approx) back. I've seen my average climb to around 8 mpg doing this. at 400hp the truck is really lacking power pulling hills. I really expected better fuel mileage out of this truck but I guess I should've stuck with Freightliner & the DD15 if I wanted fuel mileage.
