Higher trailering capability and confidence are driven by new hardware and technologies.
 
The the all-new 2020 GMC Sierra Heavy Duty combines greater trailering capability with technologies designed to provide customers with a world-class towing experience.
 
This is driven by features that include:
• An enhanced ProGrade Trailering system featuring class-leading available 15 camera views, including a segment-first transparent trailer view to virtually see through a trailer in tow.
• An available smart trailer designed to integrate the iN∙Command® control system from ASA Electronics provides the ability to monitor and control select functions of compatibly equipped trailers through the myGMC mobile app.
• A segment-exclusive available 15-inch-diagonal head-up display that offers useful trailering information, including vehicle speed, navigation information and an inclinometer display for the road grade.
• An available segment-first Rear Camera Mirror.
• MultiPro, the world’s first six-function tailgate, allows easier loading, unloading and bed access and is available on all trim levels.
• A larger, commanding design that provides more room for cargo and occupants.
• An all-new, segment-first, Allison 10-speed automatic transmission mated to the legendary 6.6L Duramax turbo diesel.
 
ProGrade Trailering Technology
First introduced with the 2019 Sierra light duty, the ProGrade Trailering System leverages technology advancements to offer additional features and functionality for the 2020 Sierra Heavy Duty.
 
“Trailering is the most important consideration for Sierra Heavy Duty customers, and the new features and technologies in the 2020 Sierra HD make it easier than ever to hitch a trailer and tow it confidently,” said Jaclyn McQuaid, vehicle chief engineer, Heavy Duty Trucks. “We’ve developed this new truck to offer the greatest trailering experience ever offered by GMC.”
 
An available class-leading 15 unique camera views1, including an industry-first transparent trailer view, help optimize the driver’s view around the truck and compatible trailers to provide added confidence when towing. The revolutionary transparent trailer feature uses the tailgate-mounted camera and an available accessory camera mounted on the rear of the trailer. The resulting display helps the driver to virtually see through the trailer, a benefit when navigating parking lots, merging into traffic or making tight turns.
