First Look: 2011 GMC Sierra 3500 HD Denali

Here's a first look at the 1-ton GMC Sierra HD Denali. It's the dual-rear-wheel version of the HD Denali three-quarter-ton shown at the NTEA Work Truck Show earlier this year, and it’s being positioned by GM to take on Ford’s F-350 King Ranch. Expect to see 1-ton Sierras at a ranch near you by the end of the year.
