700 miles on the odometer and I took a 400 mile trip in the rolling hills of central Texas this weekend. 200 miles into a 35mph headwind and I got 15.25. 200 miles back home with a 20mph tailwind got me 18.9.... It seems to be hanging around the 17.2 mpg average on the highway which is surprisingly the same as the '11 2wd that I traded in. All mileage claims were hand calculated but within .5 mpg of what the truck computer calculated.
