If folks want great mileage get a Prius.

That right foot has a lot to do with mileage ,as you guys state. I try to tell my 3 teenagers that same thing, but they seem to dismiss my advice. I will be very happy with 16 - 18 on the hwy and empty. I owned 4 PSDs (2x7.3 and 2x 6.0) and that is what I avgd with them all and I also got that with my Tundra.
