2003 Chevrolet Silverado 2500HD 4dr Extended Cab LS 4WD LB (6.0L 8cyl 5M)
Get the diesel/Allison combo! I have experienced 23-27 mpg cruising at 70 mph, 16-17 city. Even factoring in the higher price of diesel, the cost per mile has been less, and with unlimited power and towing ability. Only annoyances have been rattling steering column and body squeaks and rattles. Otherwise truck has been very reliable. Comfortable and with very good brakes and handling.
