Shucks even my previous 2005 MED-SIZE Colorado (Keep in mind this truck
is SMALLER than a SILVERADO) claimed an EPA of 20 MPG Highway, but in 2-wheel
drive mode my math showed it was getting around 17MPG, in 4-Wheel drive I
hesitate to even think about it. With their pickups there does not seem to be
much of a gap between full size and med-size in terms of MPG.
For the record, I've got an '05 4WD, ext-cab Colorado with the big engine
(3.5L 5-cyl) and I'm currently averaging 30.2 mpg. I don't think a
Silverado can do that. Even before I started hypermiling/ecomodding I got
~25 mpg.
