Our 2010 has about 16k miles on it, and i believe gets around 22 mpg. Probably be better if your foot wasnt to the floor the entire time, but thats the only way you can get anywhere in it. Barely makes it up some small small CT highway hills here at 70, nevermind with something in the back
We mostly just use it as a transportation for tools/materials to jobs and for errands. the F450s do the work
