Combined hwy/city = 15.5 to 16.5. I consider that to be pretty good especially since the company truck (2009 F250 Powerlessstroke) only gets 14mpg on the highway at 70.
Don't believe the overhead, at least on my truck it's too optimistic.

Same setup but 3500 long bed 2wd...just about the same combined. On a 350 mile trip unloaded at 70 mph I got around 18 calculated.
Ditto on the overhead
