The 2016 GMC Sierra HD is now being offered with a gooseneck/fifth-wheel trailering prep package right from the factory.
The $350 option features a frame-mounted hitch platform and tray that accommodates a gooseneck ball hitch or fifth-wheel hitch mounting brackets. The platform is concealed beneath the truck’s bed floor and, when the hitch isn’t needed, it can be removed for full use of the bed’s cargo capacity. GMC includes caps for the openings in the floor as well as a bed-mounted seven-way trailer wiring connection.
GMC is also introducing a new gooseneck completion kit. Available as a $315 accessory from GMC dealers, the kit features a 2-5/16-inch ball hitch and two chain tie-downs.
GMC dealers also offer fifth-wheel hitches from CURT Manufacturing that are compatible with the factory-installed hitch platform. They are available in 20,000-pound and 25,000-pound versions for $939 and $999, respectively (not including tax, installation and labor charges).
The 2016 Sierra HDs’ fifth-wheel trailering ratings are aligned with SAE J2807 standards and have the following maximum capacities:
- 2500HD trailering rating of 18,000 pounds (8,165 kg)
- 3500HD single-rear-wheel trailering rating of 17,500 pounds (7,938 kg)
- 3500HD dual-rear-wheel trailering rating of 23,200 pounds (10,523 kg)
The GM Authority Take
This is a very welcome addition to what is already a stellar pickup truck. We should note that the Chevrolet Silverado HD is also getting the same treatment.
