Bought my 2003 Sierra hd brand new and still use it as a daily in 2020. Best truck I’ve ever owned and don’t think I’ll ever let it go. Still in top shape . Still turns heads on the road

Not had to put and money into repairs.
It is still a great vehicle, very dependable. When I have need to move or transfer items have a vehicle available.

GMC Crewcab; the Cadillac of trucks.
The Sierra 1500HD has the 6.0 liter gas engine and performs all tasks as well as the 2500 diesel engine equipped truck. When I replace this truck it will be with another similar GMC Truck.

It is charcoal grey and unique to that year!
My truck is the top package level and it has everything I need and so much more. It has a leather heated seats and a memory setting on the driver's seat. It has four wheel drive and an entertainment area in the back. It is dependable and a daily driver!

2003 GMC sierra 1500 hd Denali.
Excellent power and performance. Rides smoothly. Tows wonderfully. Guzzles fuel, 12 mpg average. Quad steer was awesome, until it failed. Fiberglass bed side, so they will not rust. Not having control of the transfer case can be annoying, caused me to get stuck where I should not have.
