I picked up my new Dmax on Sat. 3500 Silverado Classic extra cab longbed. I tried to order an LT3 package but they have quit taking orders on the classics. I am driving home now visiting relatives along the way. MPG so far is 17.4 hand calculated. The computer shows 16.2. This truck runs great and rides like a half ton. I'm supposed to take it easy for the first 500 miles so I have to wait another 50 miles to get on it. I think I'm going to like this truck.
