What Owners are Saying About the 2005 GMC Sierra 2500 HD Extended Cab

"No Better GM Truck Out There"

"These are by far the most reliable - used trucks you will find on the market. Don't buy an 07 or newer, too many mechanical and electrical problems. GM has never been the same since the 03-06 trucks. Ultra reliable, easy to get parts, timeless body style, great work horse. Crew cabs will pull 19-20 mpg on the highway no problem (with stock suspension/wheels)."
