2007 GMC Sierra 2500HD Work Truck 4dr Extended Cab SB (6.0L 8cyl 6A)
Review
Bought the 6.0ltr WT version two weeks before leaving Maryland. Installed cruise control and hauled 5500 lbs on a 16ft tandem trailer and 1000 lbs in the bed. Averaged 16mpg on Hwy after tuning with the Diablo Predator using 87 octane gas. I have the 4:10 HD posi-lock rear. I average 12-13 mph in town. I would have liked the 6spd Allison transmission.
Favorite Features
Firm ride, drives and pulls great with the loads I've used so far.
Suggested Improvements
More pockets/compartments. Overhead storage. In bed trailer-light hook up for 5th wheels/trailers.
