The Trailering Wars Intensify

GMC announced more Pro Trailering Features available in the 2021 Sierra 1500 and Sierra HD pickup trucks, as well as a Black Diamond Edition Denali.


The world of full-sized pickup trucks is getting more and more competitive, and with it comes more technology and capability. Not only are manufactures competing for the “best-in-class” towing and payload numbers, but also in the tailgate wars and trailering tech.
To step up their game against competition from Ford and Ram, GMC announced today 5 new trailering enhancements on their 2021 Sierra line:
Select trailering features require a conventional-hitched box or camping trailer and additional setup may be required. Customers can see their dealers for full details.
We mentioned the tailgate wars above, and GMC is not standing idly by. GMC, with their MulitPro multi-function tailgate was the pioneer of the Swiss-Army-Knives of tailgates and has extended availability down to the Elevation and SLE trims. Just as Chevrolet announced they are borrowing the feature on their Silverado and dubbing it the “Multi-Flex Tailgate.”
Three new colors will be available on Sierras and the off-road capable 1500 Sierra AT4 will have additional options of a 20-inch Goodyear Wrangler Territory tire package and off-road high-clearance step.
The available 3.0L Duramax Turbo-Diesel, which provides an ideal balance of performance and efficiency with 460 lb-ft of torque and best-in-class horsepower while offering up to an EPA-estimated 30 mpg on the highway, is a popular choice for GMC Sierra customers. For 2021, the MSRP of the popular engine will be reduced by $1,500, placing it at $995 MSRP above the Sierra 1500’s 5.3L V-8 with Dynamic Fuel Management.
New additions to the 2021 GMC Sierra Heavy Duty include enhancements to the trucks’ popular premium trims. HD Surround Vision and Bed View camera technology are now standard on Denali. The new Sierra HD Denali Black Diamond Edition will have several unique features, including exclusive 20-inch high-gloss black wheels and new power-retractable assist steps.
Similar to the Sierra 1500, the Sierra Heavy Duty AT4 will now have available 18-inch Mud Terrain tires and an available off-road high clearance step accessory.
