"We procured similarly equipped trucks from Ford, Ram and GMC and put them through the paces towing up and down some of the toughest grades in the country covering a total of 2,200 miles," said Mike Levine, editor of PickupTrucks.com. "When we analyzed the data, the GMC Sierra 3500HD simply outperformed the trucks from Ford and Ram."
"Customers choose full-size trucks for their capabilities," said Rick Spina, vehicle line executive for full-size trucks. "So for 2012, we built on the foundation created in 2011, with engineering changes and additional validation designed to make the most capable heavy-duty pickup even better. Based on PickupTrucks.com's test results, it looks like we got the job done."
