Conventional wisdom has it that big trucks are an endangered species. If so, don’t tell it to Detroit makers, who’re unleashing an assortment of macho machines designed for those with serious towing and hauling needs.
Coming a month after the Chicago Auto Show debut of the new heavy-duty Chevy Silverado, General Motors’ other truck brand weighs in at the St. Louis Auto Show with the 2011 GMC Sierra Denali HD. It’s the first time the Denali name has been bolted onto a heavy-duty GMC pickup.
Along with the 2011 GMC Sierra 2500HD and 3500HD trucks, the Sierra Denali HD weighs in with an all-new frame and upgraded suspenion package.
