The 2006 Chevrolet Silverado has an angry, angular appearance that is softened on the redesigned 2007 version. Historically, the Silverado has shared its appearance with the Avalanche pickup and/or the Suburban/Tahoe SUVs. This time around, though, the Silverado will get a unique look. Currently, the maximum tow rating for the 1500-series models is 10,400 pounds, while the heavy-duty HD-series can tug as much as 12,000 pounds.
