I'm very disappointed with my '05. I had a '01 that was getting between 22 and 24 MPG when I drove between 65 and 75 on the highway. It got 18 - 19 in town. With my '05 that now has 18K miles, I'm lucky to get 16 MPG on the highway and 14.9 in town. Frankly, the power difference between the two trucks pulling a 14K lb load is not that noticable to me (which draws me down to 11 MPG). Hence, I spent $20K to get a new CD player and tires -- while giving up 5 - 6 MPG. My dealer indicates that it is a known problem for GM, and that they are working on a software fix. I believe that to be a load of crap. I love the ride and style of the truck, but this economy is making me consider switching to (God Help Me) ... a Ford. My dad has the same truck with a Ford emblem that is regularly posting 23 MPG on the highway.
