The Exciting Features of the Redesigned 2020 GMC Sierra 3500HD Available Near Elgin

  • Best towing yet. Towing prowess is probably the most exciting of the updates made to this year's model. Where previously, this version of the Sierra was capable of towing trailers, campers, and other towables weighing up to 23,100 pounds, the 2020 GMC Sierra 3500HD can tow an incredible 35,000 pounds. That's a more than 10,000-pound improvement that took this model from the middle-of-the-pack to class leader! This massive number change was due in part to better engine offerings and part to new trailer-towing technologies that make towing those heavy items easier on the vehicle and the driver.
  • Exciting cargo bed features. Of course, not everything you want to haul needs to be towed. In addition to high towing capabilities, this model also offers high hauling capabilities in its cargo bed. In fact, thanks to this year's redesign, this model now features the best in its class cargo bed volume. When you choose the largest bed option, you can enjoy an incredible 83.5 cubic feet of volume. Additionally, that bed is comprised of roll-formed high-strength steel with a durable spray-on bedliner for maximum durability no matter what you're hauling. Twelve cargo tie-downs also make it easy to strap loose items down for fast and safe transportation.
  • Maximum interior class. Prefer passenger room to cargo room? Then ask our sales associates about the very spacious GMC Sierra 3500HD with Crew Cab. This version of the model features the most interior space for a crew cab in this class. Both the front and rear seats offer an incredible amount of head and legroom so that everyone can stretch out and get cozy for those long trips away from Elgin.
