Quick Answer
A 2026 Chevrolet Silverado 3500 HD Crew Cab long bed 4WD with single rear wheels and the Duramax is rated 20,000 lb on a ball hitch and 21,490 lb on a gooseneck, properly equipped. Payload for that configuration starts from 4,309 lb; the door-jamb label gives the exact figure.
Most one-ton conversations at our desk start with the word dually. A good share of them should not. A 2026 Silverado 3500 HD LT on single rear wheels and a High Country dually can share the same cab, bed, drive and engine, built two different ways. This post is about the first truck: what it is rated to pull, where the single-rear-wheel ceiling sits, what equipment does to payload, and when to move to the dually instead.

Why it can have a Z71 and a dually cannot
What Exactly Is a Single-Rear-Wheel Silverado 3500 HD Crew Cab?
Configuration first, because every rating depends on it. The truck in this post is a 2026 Silverado 3500 HD LT, Crew Cab, long bed, four-wheel drive, single rear wheels, with the Duramax 6.6L Turbo-Diesel V8 and the 10-speed automatic. Its options include the Z71 Off-Road Package, 20-inch wheels and the gooseneck and fifth-wheel prep package.
That is the one-ton a lot of outfits around Mobridge actually run: a crew cab for the family, a long bed with a ball for the stock trailer, four-wheel drive for the yard in March, and a body still 81.85 in wide. The Duramax is rated 470 hp and 975 lb-ft.
If you are still deciding between it and the dually, our single rear wheel or dually comparison runs that decision start to finish. Here we stay with the single-rear-wheel truck.
What Is a Single-Rear-Wheel Silverado 3500 HD Rated For?
For a 2026 Silverado 3500 HD Crew Cab long bed 4WD with single rear wheels, Chevrolet rates the two engines as follows, properly equipped.
| Crew Cab long bed 4WD, single rear wheel | Duramax diesel | 6.6L gas V8 |
|---|---|---|
| Conventional (ball hitch) | 20,000 lb | 16,000 lb |
| Gooseneck | 21,490 lb | 18,230 lb |
| GVWR | 12,250 lb | 11,700 lb |
| Combination rating (GCWR) | 30,000 lb | 26,000 lb |
| Rear axle rating | 7,250 lb | 7,250 lb |
| Payload, base configuration | starts from 4,309 lb | starts from 4,472 lb |
The payload row needs the most care. Those figures are for a base-equipped truck, and every factory option comes out of them. An LT with the Z71 Off-Road Package, 20-inch wheels and tires, the gooseneck prep and a long list of comfort equipment has a payload lower than 4,309 lb. Its exact figure is on the label in its driver door jamb, the final word on any individual truck.
For reference, a single-rear-wheel High Country of the same configuration has its own published figures: 3,924 lb of payload and 21,200 lb on a gooseneck with the Duramax, properly equipped. Full tables by cab and bed are in the towing section of the 2026 Silverado 3500 HD buyers guide.
How to read the door-jamb label
Open the driver door and look at the B-pillar. The tire and loading label states the most the occupants and cargo may weigh combined; that is this truck's payload as built. The Trailering Information Label on the same door jamb lists the truck's trailer and tongue weight ratings. Take a photo of both before you sign anything, and run your trailer against them, not against a brochure.
Can You Tell From a Listing Whether a Silverado 3500 HD Is a Dually?
Not from the headline. "Silverado 3500 HD LT Crew Cab long bed 4WD" describes a single-rear-wheel truck and a dually equally well, and a front three-quarter photo can hide the rear fenders. Four things in a listing settle it.
- The equipment list. Look for the words "single rear wheels" or "dual rear wheels".
- The GVWR. Every 2026 Silverado 3500 HD dually carries a 14,000 lb GVWR. A single-rear-wheel truck tops out at 12,250 lb.
- The wheels and tires. A dually rides on LT235/80R17E or LT235/80R18 tires. Any 20-inch wheel means single rear wheels, because Chevrolet does not offer one on a dually.
- The bed. A dually is always a long bed. A Crew Cab standard bed is a single-rear-wheel truck every time.
If none of those are listed, call or text before you drive over; 14.90 in of extra width is a bad surprise in a parking lot.
What Is the Most a Single-Rear-Wheel Silverado 3500 HD Can Pull?
22,420 lb on a gooseneck, on a 2026 Silverado 3500 HD Regular Cab long bed 2WD with single rear wheels and the Duramax, properly equipped. That is the single-rear-wheel ceiling, and it belongs to the lightest single-rear-wheel truck in the lineup, not the fanciest.
The same Regular Cab is also the exception on a ball hitch: a single-rear-wheel Regular Cab is rated 14,500 lb conventional with either engine, where every other single-rear-wheel Duramax configuration reaches 20,000 lb. So the truck with the best gooseneck number has the worst bumper-pull number. If you pull both kinds of trailer, that matters.
For a crew cab, the best single-rear-wheel gooseneck rating is 22,070 lb, on a Crew Cab long bed 2WD Duramax. The best four-wheel-drive Crew Cab is 21,600 lb, on the standard bed. A long bed 4WD sits at 21,490 lb, properly equipped. The spread across every single-rear-wheel Duramax crew cab, High Country included, is 870 lb, so the cab and drive you need should decide the truck, not the rating.
One more line worth knowing if you are pricing the gas engine. On a Crew Cab long bed 4WD, the gas dually's gooseneck rating, 17,800 lb, is lower than the gas single-rear-wheel truck's 18,230 lb, properly equipped. A gas dually earns its keep in payload, not in trailer rating.
Why Can a Single-Rear-Wheel 3500 HD Have a Z71 When a Dually Cannot?
Because Chevrolet does not offer the Z71 Off-Road Package with dual rear wheels on any trim. The same goes for 20-inch wheels, the Trail Boss Package, the Midnight Edition and the Stars and Steel editions. If you want the off-road equipment or the bigger wheel on a one-ton, you are buying single rear wheels.
Two builds show the rule. An LT with the Z71 package and the 20-inch wheels is a single-rear-wheel truck. A High Country dually has neither and rides on 18-inch polished forged wheels, but it keeps the leather, the head-up display, the power sunroof and the gooseneck prep. The full list of what a dually can and cannot be ordered with is in what a 2026 Silverado dually gives up, and what it keeps.
Who Should Buy Single Rear Wheels, and Who Should Not?
The decision comes down to kingpin weight against payload, not the tow rating. Chevrolet recommends a gooseneck or fifth-wheel kingpin load of 15 to 25 percent of the trailer's weight, and a tongue load of 10 to 15 percent on a ball hitch. All of that sits in the bed and comes out of payload before anyone climbs in.
Here is an illustration, not a quote for any truck. Say your loaded gooseneck stock trailer scales at 15,000 lb. At 15 percent, 2,250 lb rides on the ball; at 25 percent, 3,750 lb. Add 500 lb for two people, a dog and the gear in the back seat, and you need between 2,750 and 4,250 lb of payload. The low end fits a single-rear-wheel Crew Cab easily. The high end runs right up against the 4,309 lb base figure, and an equipped truck has less than that. That trailer, loaded heavy on the pin, is a dually's job; a High Country dually is rated for 5,378 lb of payload, properly equipped.
Run the same arithmetic on a 10,000 lb bumper-pull: 1,000 to 1,500 lb on the tongue, comfortable inside a single-rear-wheel truck's payload with room for the crew.
| Single rear wheels are worth it if | Skip them for a dually if |
|---|---|
| Your kingpin plus cab load fits inside the door-jamb payload with margin On the Duramax, you pull bumper trailers up to 20,000 lb and goosenecks under 21,490 lb The truck is also the daily driver, school run and parts run Your shop door, car wash or fuel island is tight at 96.75 in You want the Z71 package or a 20-inch wheel |
Your loaded kingpin runs 3,500 lb or more You haul a loaded gooseneck near the rating every week You want the 10,400 lb rear axle rating and 14,000 lb GVWR You run a living-quarters or toy-hauler fifth wheel with a heavy pin You haul for hire and want the margin on paper |
From the Beadle Chevrolet GMC Lot
The question we hear most about this truck is whether it will pull a gooseneck. On paper it almost always will. The conversation that actually decides it is how much of that trailer ends up on the pin, and that is a payload question. We would rather open the door, read the label with you and run your trailer against it than have you guess from a headline.
What Does a Bale Bed, Flatbed or Plow Do to the Arithmetic?
It takes from the same pile. A toolbox, a transfer tank, a plow, or a bale bed or flatbed in place of the box all count against payload before the trailer's kingpin does, and that equipment never comes off.
The door-jamb label describes the truck as built. Once you bolt equipment on, a scale ticket of the truck as you will run it, full of fuel, against the GVWR on the label tells you what is left. Chevrolet offers snow plow prep from the factory, and a plow sits out front on the front axle, so ask us to check the front axle rating on the specific truck too.
Body weights vary by builder, so we do not publish them here. If a bale bed or flatbed is in your plan, bring the body maker's published weight to the desk and we will work through what the truck has left.
How to Check Your Trailer Against a Single-Rear-Wheel 3500 HD
Five steps, about fifteen minutes with a scale ticket in hand.
- Weigh the trailer loaded. Use the heaviest load you actually haul, at the sale barn scale or the elevator, not the empty weight on the trailer's plate.
- Work out the pin or tongue load. Take 15 to 25 percent for a gooseneck or fifth wheel, 10 to 15 percent for a bumper-pull, and plan from the top of the range.
- Add everything else in the truck. People, dogs, tools, mineral tubs, a toolbox or transfer tank, and any body or plow.
- Compare against the door-jamb payload. Read the label on the exact truck. If the total is over it, or within a few hundred pounds, look at the dually.
- Check the trailer rating and the GCWR. 21,490 lb gooseneck and 30,000 lb combined on a Crew Cab long bed 4WD Duramax, properly equipped.
Or bring the trailer to 2200 US Hwy 12. We will read both labels with you and tell you plainly if the dually is the better buy.
Our Recommendation
For a Mobridge-area cow-calf operation pulling a gooseneck stock trailer that scales 15,000 lb or less loaded, we recommend the single-rear-wheel Silverado 3500 HD Crew Cab long bed 4WD Duramax: 21,490 lb on a gooseneck and 20,000 lb on a ball, properly equipped, in a body 14.90 in narrower than the dually. Once the pin load plus the crew crowds the payload on the label, step over to the dually.
Key Takeaways
A 2026 Silverado 3500 HD Crew Cab long bed 4WD with single rear wheels and the Duramax is rated 20,000 lb conventional and 21,490 lb gooseneck, properly equipped.
Payload for that configuration starts from 4,309 lb with the Duramax; options such as the Z71 package and 20-inch wheels reduce it, and the door-jamb label gives the exact figure.
The single-rear-wheel ceiling is 22,420 lb on a gooseneck, on a Regular Cab long bed 2WD Duramax; the best crew cab is 22,070 lb.
Kingpin load of 15 to 25 percent of the trailer, plus everything else in the truck, decides single rear wheels or dually.
Z71, Trail Boss, Midnight Edition, Stars and Steel and every 20-inch wheel are single-rear-wheel only.

My Take on the Single-Rear-Wheel One-Ton
I think the single-rear-wheel 3500 HD is the most underrated truck in the lineup. People hear one-ton and picture a dually, but a lot of the trailers around Mobridge, from the stock trailer headed to the sale barn to the boat going to Lake Oahe, fit comfortably inside what this truck is rated for, and it is a far easier truck to live with on US 12, in town and in the shop.
Where I push people toward the dually is when the pin weight and the crew start crowding the payload on the label. That is arithmetic, not a sales pitch, and I would rather show you the math than have you find it at a scale. The single-rear-wheel section of our 2026 buyers guide has every rating if you want to check us.
