Kaufman, TX
If you’re hauling a heavy trailer around Kaufman, TX, you need a truck that can handle the job without breaking a sweat. At Brinson Chevrolet, we get asked all the time: “How much can these heavy-duty Silverados actually tow?” It’s a great question — and the answer depends on a few key factors. Here’s everything you need to know about the towing muscle behind the 2025 Silverado 2500HD and the 2025 Silverado 3500HD.
The 2025 Silverado 2500HD is rated to tow up to 20,000 lbs. for conventional trailering when equipped with the Duramax 6.6L Turbo-Diesel V8 and the Max Trailering Package on properly equipped configurations. The 6.6L V8 gas engine tops out at 18,500 lbs. of conventional towing in its most capable setup.
The 2500HD offers two engine choices: the 6.6L V8 Gas (401 horsepower, 464 lb.-ft. of torque) and the Duramax 6.6L Turbo-Diesel V8 (470 horsepower, 975 lb.-ft. of torque). That torque advantage is what really separates the two when you’re pulling heavy loads.
For fifth-wheel and gooseneck towing, the diesel-equipped 2500HD with the Max Trailering Package can hit up to 22,420 lbs. in certain configurations. Across the board, the Duramax diesel consistently outperforms the gas engine in every towing category — conventional, fifth-wheel, and gooseneck. And keep in mind that your actual number will vary depending on cab style, bed length, drivetrain (2WD vs. 4×4), and wheel size. That’s why it’s always worth looking at Chevy’s official trailering charts for your exact setup.
2025 Silverado 2500HD Conventional Towing Highlights:
The Silverado 3500HD is built for heavier commercial and agricultural work, and its towing numbers reflect that. In conventional trailering, both trucks can hit 20,000 lbs. in their top configurations — but the 3500HD steps ahead dramatically when it comes to fifth-wheel and gooseneck work, reaching up to 36,000 lbs. with the Duramax diesel and Max Trailering Package on a dual rear wheel (DRW) setup.
The 3500HD is also available in a dual-rear-wheel (DRW) configuration, which isn’t available on the 2500HD. That extra set of rear tires adds serious stability and load capacity — especially useful if you regularly run a heavy fifth-wheel or gooseneck trailer. What is the difference in towing capacity between the Silverado 2500 and the Silverado 3500? In short, for most conventional trailer work, they’re close. But if you’re in the gooseneck or fifth-wheel world, the 3500HD is in a different league.

Yes — and it’s not particularly close. Does the Duramax diesel tow more than the 6.6L gas engine? Across every cab, bed, and drivetrain combination, the Duramax consistently outperforms the gas V8 in both conventional and fifth-wheel/gooseneck ratings.
The Duramax 6.6L Turbo-Diesel V8 produces 470 horsepower and 975 lb.-ft. of torque. The 6.6L V8 Gas produces 401 horsepower and 464 lb.-ft. of torque. of torque. That gap — more than 500 lb.-ft. of torque — is what you feel when you’re pulling a loaded livestock trailer up a Texas grade. Torque is what moves weight, and the Duramax delivers it in abundance. If you’re going to be towing heavy loads regularly, the diesel is almost always the smarter long-term choice. You’ll also typically see better fuel economy under load compared to the gas engine.
This is where the 3500HD really separates itself. What is the maximum gooseneck and fifth-wheel towing capacity on the Silverado 3500HD? When you go with the Duramax 6.6L Turbo-Diesel V8, the Max Trailering Package, and a dual-rear-wheel (DRW) configuration, the 3500HD can tow up to 36,000 lbs. via a gooseneck or fifth-wheel hitch.
Even with a single rear-wheel (SRW) setup and the diesel, fifth-wheel/gooseneck numbers on the 3500HD can reach into the low- to mid-30,000-lb range. range depending on your specific configuration. The gas engine on the 3500HD is rated up to around 22,070 lbs. fifth-wheel/gooseneck. These are serious numbers for serious work — whether that’s a heavy equipment trailer, a large RV, or commercial hauling.
It depends on the horse trailer and how many horses you’re hauling. Do I need the 2500 or 3500 if I am towing a horse trailer? For lighter bumper-pull trailers (say, a two-horse trailer under 8,000–10,000 lbs. loaded), the 2500HD with the gas engine is plenty of truck. But as soon as you move into larger gooseneck-style horse trailers — especially those carrying four or more horses with living quarters — you’re often looking at 15,000–20,000+ lbs. loaded, and the 3500HD with the Duramax diesel becomes the right call.
Living quarters trailers, in particular, add significant weight quickly. A six-horse slant with full LQ can easily hit 20,000+ lbs. when loaded. In that case, the 3500HD DRW with the Duramax isn’t just better — it’s the safe and appropriate choice. If you’re hauling horses in East Texas and you’re not 100% sure which truck fits your setup, our team at Brinson Chevrolet in Kaufman can walk you through it.
Yes, and this is one of the most overlooked pieces of the puzzle. Does towing capacity change based on cab size and bed length? Absolutely. Chevy’s official trailering charts show different ratings for Regular Cab, Double Cab, and Crew Cab configurations, as well as Standard Bed vs. Long Bed — and those differences can be significant.
On the 2500HD, for example, a Regular Cab Long Bed 2WD with the Duramax diesel often carries a higher tow rating than a Crew Cab Short Bed 4×4 with the same engine. Why? Wheelbase, rear axle weight ratings, and overall GCWR (Gross Combination Weight Rating) all come into play. Drivetrain matters too: 2WD configurations sometimes allow slightly higher tow ratings than comparable 4×4 trucks due to differences in component weight. The bottom line: don’t assume your buddy’s number applies to your truck.
The best way is Chevy’s official trailering capacity charts, which break down the trailering capacity for every engine, cab style, bed length, drivetrain, and wheel configuration side by side. How do I find the towing capacity for my specific Silverado 2500 or 3500 configuration? Start there, and then cross-reference with your door jamb sticker or owner’s manual for your VIN-specific ratings.
