GMC Sierra 3500HD wins PickupTrucks.com "HD Hurt Locker" comparison test
Our friends at PickupTrucks.com have just completed their "HD Hurt Locker" comparison test, in which the GMC Sierra 3500HD, Ford F-350 and Ram 3500 were put through quite a series of tests. PickupTrucks.com editor Mike Levine called it a "grueling showdown among industry heavyweights that included towing 19,000-pound fifth-wheel trailers up and over some of the most demanding grades in the United States."
