Used 2007 Chevrolet Silverado Classic 1500 2LS Crew Cab RWD for Sale near Barnes, KS

We tested the gas mileage in several ways but, keep getting the same results. In town, the best gas to the cheapest gas was only 12 MPG. On the Highway, our biggest accomplishment was at 17 MPG. General Motors said the estimated sticker mileage quote was just a theoretical statement. At 45 to 55 MPH the truck has this vibration and in curves at a lower speed it has this same vibration. If driven from payment to concrete or a bumpy road the truck will dance and shake.
