General Motors unveils the new medium-duty trucks Chevrolet Silverado 4500HD, 5500HD and 6500HD at the NTEA Work Truck Show in Indianapoli. These Class 4, 5 and 6 trucks will replace the Chevy Kodiak and GMC TopKick models, which were discontinued in 2009. That puts the latest Chevy trucks back in direct competition with the Ford F-450/F-550 and F-650/F-750, and the Ram 4500/5500 Tradesman.
