Fun to drive and very versatile
By Donald E. Gradeless on


2003 GMC Sierra 1500HD 4dr Crew Cab SLE Rwd SB (6.0L 8cyl 4A)


Special Ordered 2WD with all options except the OnStar and XM Radio. Commuting in city to work average 17 mph, 15 on trips, 11.8 towing 34' Avion has 4.10 axle. Will get 22 mpg @ 50 mph but who can drive 50! Several build issues & recalls but great truck except am now getting noise from the rear emergency brake drum caused by not using the parking brake and told its common problem with GM 4 Wheel Disk Brakes rusting from non use. First trip from Indiana to Ruidoso NM we averaged 12.1 going and 11.8 returning with 34' Avion in tow with temp at 112° in NM. Great fiberglass bed, electronic suspension, dual memory driver setting, free extension for the rear safty belts. Love computer display

Best Features

First towing at 112° at Roswell NM & cruise held full speed with 34' Avion. Can turn unbelievably tight with Quad Steer. Fun accelerating thru curves as Electronic suspension lifts the truck and Quad Steer makes you feel like you are on rails as you speed up. Quad steer tricky

Worst Features

Would love a 2 speed rear axle to improve mileage. fantastic gas mileage for size of vehicle until you get over 50 mph. 6 speed transmission would also help. Less plastic on the interior. Needs to adjust the angle of the back rest in the rear seats.
