Also, I've only had it five days and 800 miles, but the computer, assuming it's accurate, is consistently showing 20 MPG. Pretty impressed with that mileage for such a large vehicle!
That's pretty darn impressive. I half a half ton Ram that only seems to get 19 MPG on the highway, which has been disappointing for me, since my pops has about the same truck, just a couple years older, and seems to turn 26 on the highway.
