Gas mleage is remarkable for a large truck with the 5.3 l engine. I typically average 18.9 combined driving and 20.2 on long interstate trips and have measured it numerous times. I test drove all the trucks on the market and this is hands down he best on the market. The quietness, comfort, handling, audio system is just simply the best on the market.

I have loved Chevrolets and GMCs for 30 years. My 03 Chevy Silverado was the best truck I have ever had. The 08 GMC has been the most disappointing truck I have ever purchased. I am constantly getting alarms that include: Park assist off, air bag, low tires when they are not. On top of the alarms that the dealer cannot fix I have had two interior fans replaced and they are rattling again. The motor is tapping even though I do the recommended everything. The ABS brakes act like I am on ice on dry road. Cheaper braking system. Already have warped discs. My o3 brakes went 144K miles. The sun visors are not wide enough to block the sun. Cannot handle the same trailer as the 03.

Bought pickup through GM Employee Pricing sale and got very good deal. Not quite sure about pickup, as you can feel the 4 and 8 cylinder activating and de-activating. I have experienced the tranny jerk from a complete stop as well. After changing oil I can smell oil in the cabin for at least the first 1,500 miles before going away, cannot find any leaks anywhere.

Have driven GMC trucks for several decades, this is quite possibly the best I have ever owned. Quiet ride, strong frame, good power and torque, no cheap interior like Toyota. Best looking truck on the market. I drive over railroad tracks every day, completely unnoticeable in this truck. Love the OnStar and XM radio features. Lots of interior room as I am a large person, yet fit comfortably inside

I have owned this truck for three weeks. This is my first truck and am loving it. We chose the Sierra over the Tundra. Both trucks are very quiet with smooth car-like ride and handling. Sierra got the nod because of ease of access and interior design. So far, I have averaged 16 mpg in non-freeway driving.
