Quick answer
- For a loaded gooseneck stock trailer in Tulsa, the 6.6L Duramax with the Max Trailering Package pulls up to 22,050 lbs gooseneck or fifth-wheel, in Regular Cab or Crew Cab long-bed form.
- The Duramax makes 470 hp and 975 lb-ft through an Allison 10-speed automatic. The standard 6.6L gas V8 makes 401 hp and 464 lb-ft.
- Conventional bumper-pull maxes are 20,000 lbs on the Duramax with Max Trailering and 16,000 lbs on the gas V8.
- A gas Crew Cab carries a confirmed 3,426 lbs of payload, which is what a gooseneck pin weight actually comes out of.
- An integrated trailer brake controller is standard on every 2026 trim. We stock the 2500HD; pricing starts at $45,900 for the WT.
If you are hauling livestock on a gooseneck around Green Country, the 6.6L Duramax Silverado 2500HD with the Max Trailering Package is the truck, rated up to 22,050 lbs gooseneck or fifth-wheel in a long-bed Regular or Crew Cab. The gas 6.6L V8 is the right call instead when your trailer is lighter and your annual miles are low, because it puts 401 hp under you for roughly eleven thousand dollars less up front.
That is the headline, but the number that actually decides your build is pin weight, not tow rating. A gooseneck puts a much larger share of its load straight down over the rear axle than a bumper-pull does, and that weight lands on your payload. We sell these to people running cattle and horses out of Wagoner County and down toward Okmulgee, so here is the order of operations we use at the desk. The full page-by-page detail lives on our Chevrolet Silverado HD research hub.
Pin weight is the number that bites
Conventional bumper-pull tongue weight runs roughly 10 to 15 percent of the loaded trailer. A gooseneck or fifth-wheel typically runs meaningfully higher, and all of it sits on the truck rather than behind it. That is the whole reason the HD exists, and it is why the payload figure matters more than the tow figure once you go gooseneck.
Concretely: a gas Crew Cab 2500HD carries a confirmed 3,426 lbs of payload, and the platform is rated to a GVWR of up to 11,900 lbs. Your pin weight comes out of that allowance first. Then the four of you in the cab, the tack, the feed, the water and whatever else rides in the bed come out of what is left. A stock trailer that looks well inside a 22,050-lb tow rating can still put you close on payload once it is genuinely loaded.
So read the payload sticker in the door jamb of the specific truck, not the brochure. Every build has its own number, and cab, bed and engine choice all move it. Our 2026 Silverado HD overview lays out the trim and cab combinations, and the Silverado HD FAQ answers the towing and payload questions we field most.
Duramax or the gas 6.6L
Two engines, and the split is cleaner on an HD than on a half-ton.
- 6.6L Duramax turbo-diesel V8, 470 hp and 975 lb-ft, Allison 10-speed automatic. Up to 22,050 lbs gooseneck or fifth-wheel and 20,000 lbs conventional, both with the Max Trailering Package. Available on every trim. That torque figure is the reason a loaded gooseneck feels unbothered on a grade, and the Duramax carries a longer powertrain warranty at 5 years or 100,000 miles.
- 6.6L gas V8, 401 hp and 464 lb-ft, 10-speed automatic. Up to 16,000 lbs conventional with 18, 20 or 22-inch wheels. It is the value play, it costs less to service, and for a two-horse or small stock trailer that goes out most weekends rather than every day, it is genuinely enough truck.
One ordering note worth more than it sounds: the integrated trailer brake controller is standard on every 2026 trim, so you are not shopping trims to get it. How it behaves and why a factory unit beats an aftermarket one is covered on our Silverado HD trailer brake controller guide.
What hauling stock around here actually asks
The run into Expo Square for a show or a sale is the honest test of a stock trailer rig, and it is not a horsepower test. It is stop-and-go on arrival, a long uphill pull off the fairgrounds approach, and a lot of low-speed maneuvering in gravel and mud with live weight shifting behind you. That is where the Allison’s low-speed calibration and the factory brake controller earn their money.
The other reality is heat and distance. A haul down toward Okmulgee or out through Coweta in an Oklahoma summer puts sustained load on cooling and transmission temperatures, and live animals in the trailer mean you cannot simply pull over and wait it out. Trucks that tow in this climate need their service intervals kept honestly, because fluids and filters age faster under load. The schedule and warranty terms are on our Silverado HD service schedule, and you can schedule service with our Chevrolet-certified technicians.
Bed length is the last practical piece. The standard bed measures 82.25 inches and the long bed 98.27 inches, and the long bed is what unlocks the 22,050-lb gooseneck rating. If a gooseneck is the plan, order the long bed.
See the 2500HD inventory we have on the ground and we will pull the payload sticker on any of them before you commit.
So which 2500HD should you order?
For most people hauling stock, it is a Duramax LT Crew Cab long bed. Match the truck to the trailer:
- If you run a loaded gooseneck regularly, Duramax plus Max Trailering plus the long bed. That is the 22,050-lb combination, and nothing else in the lineup reaches it.
- If your trailer is lighter and goes out on weekends, the gas 6.6L at 16,000 lbs conventional does the work and leaves money in your pocket. The WT starts at $45,900 before destination and is the most accessible way into the HD lineup.
- If the truck is also the family vehicle, step to LT or LTZ for the 13.4-inch screen and the interior you will actually want on a four-hour haul.
- If you run unimproved ground and pasture roads, the ZR2 brings the off-road hardware without giving up HD capability.
Cross-shopping the Super Duty is fair and we would rather you do it with real numbers, so we put them side by side on our Silverado HD vs Ford Super Duty comparison. And if it turns out your trailer never really needed an HD, our Silverado 1500 research hub covers the half-ton side.
Frequently asked questions
How much can a 2026 Silverado 2500HD pull on a gooseneck?
Up to 22,050 lbs gooseneck or fifth-wheel with the 6.6L Duramax and the Max Trailering Package, in Regular Cab or Crew Cab long-bed form.
What warranty does the Silverado 2500HD carry?
Three years or 36,000 miles bumper-to-bumper, five years or 60,000 miles on the gas powertrain, and five years or 100,000 miles on the Duramax diesel powertrain. Rust-through cover runs six years or 100,000 miles, and roadside assistance five years or 60,000 miles.
How much payload does a 2500HD have?
A gas Crew Cab carries a confirmed 3,426 lbs, on a platform rated to a GVWR of up to 11,900 lbs. Gooseneck pin weight, passengers and cargo all come out of that figure, so read the door-jamb sticker on the specific truck.
Do I need the diesel?
If you pull a loaded gooseneck regularly or cover long distances, yes: 975 lb-ft, the Allison 10-speed, the 22,050-lb rating and a 5-year/100,000-mile powertrain warranty. For lighter trailers and lower annual miles, the 401-hp gas V8 is the better value.
Does the 2500HD come with a trailer brake controller?
Yes. An integrated trailer brake controller is standard on every 2026 trim, not an option package.
