GMC builds trucks for every kind of job, from quick runs to the hardware store to pulling a fifth-wheel RV across the country. If towing sits at the top of your list, the right GMC depends on how much weight you plan to pull and how often.

This ranking walks through the 2026 GMC truck lineup from the heaviest hauler to the most agile, so you can match a truck to the trailer in your driveway. Every figure below is a maximum rating for a properly equipped truck.

2026 GMC trucks ranked by maximum trailering

GMC Truck	Maximum Trailering	Setup
Sierra 3500HD	36,000 lbs (16,329 kg)	Gooseneck/5th-wheel, Duramax diesel
Sierra 2500HD	22,430 lbs (10,174 kg)	Gooseneck/5th-wheel, Duramax diesel
Sierra 1500	13,300 lbs (6,033 kg)	Conventional hitch
Sierra EV	12,500 lbs (5,670 kg)	Conventional hitch
Hummer EV Pickup	12,000 lbs (5,443 kg)	Conventional hitch
Canyon	7,700 lbs (3,493 kg)	Conventional hitch

A quick note on the numbers: the Sierra HD trucks hit their peak with a gooseneck or fifth-wheel hitch mounted in the bed. The Sierra 1500, Sierra EV, Hummer EV Pickup, and Canyon figures are conventional hitch ratings.

Sierra 3500HD: the heavy-duty champion

The Sierra 3500HD sits at the top for a reason. With the available 6.6L Duramax Turbo Diesel V8 and the Max Trailering Package, a properly equipped 3500HD pulls up to 36,000 lbs (16,329 kg) using a gooseneck setup. On a conventional hitch, it still rates up to 20,000 lbs (9,072 kg).

This is the truck for large fifth-wheel RVs, equipment trailers, and commercial loads that would overwhelm lighter pickups.

Sierra 2500HD: serious capability, easier to live with

Step down to the Sierra 2500HD and the numbers stay strong. With the Duramax diesel and Max Trailering Package, it tows up to 22,430 lbs (10,174 kg) on a gooseneck and up to 20,000 lbs (9,072 kg) conventionally.

The 2500HD suits owners who tow heavy travel trailers or large boats but want a truck that is a little more manageable day to day than the 3500HD.

Sierra 1500: the everyday workhorse

The Sierra 1500 covers the widest range of needs. With the available 3.0L Duramax Turbo Diesel inline-six, Max Trailering Package, and 20-inch wheels, it tows up to 13,300 lbs (6,033 kg) on a conventional hitch.

That is enough for most boats, utility trailers, and mid-size travel trailers, all in a half-ton truck that handles commuting and family duty with ease.

Sierra EV and Hummer EV Pickup: electric muscle

GMC’s electric trucks prove that going electric does not mean giving up towing. The Sierra EV pulls up to 12,500 lbs (5,670 kg) and offers up to 660 km of GM-estimated range, pairing real capability with long legs between charges.

The Hummer EV Pickup tows up to 12,000 lbs (5,443 kg) and leans into off-road adventure with its multi-motor drive and up to 824 km of GM-estimated range. Both deliver instant electric torque for confident pulling.

Canyon: midsize and ready for adventure

The Canyon rounds out the lineup as the midsize option. With the TurboMax engine, a trailering package, and a limited-slip differential, it tows up to 7,700 lbs (3,493 kg).

That makes it a strong match for smaller trailers, off-road toys, and weekend campers, in a truck that is easier to park and live with than a full-size pickup.

• Large fifth-wheel RVs and heavy equipment: Sierra 3500HD or 2500HD
