What truck can tow 40,000 lbs?
No current production pickup truck is rated to tow 40,000 pounds in its standard factory specifications. The heaviest conventional pickups top out around the high 30,000s with specialized 5th-wheel or gooseneck configurations, while truly 40,000-pound towing capacity generally requires a larger commercial truck or semi-trailer pairing.
The reality: what current trucks can pull near 40,000 pounds
To illustrate the practical ceiling for today’s consumer-grade heavy‑duty pickups, here are the top-rated gooseneck/5th-wheel towing figures published by manufacturers. These numbers assume optimal configurations, appropriate hitching, and compliant trailer setups.
- Ford F-450 Super Duty (6.7L Power Stroke) — Up to about 37,000 pounds with gooseneck/5th-wheel towing
- Chevrolet Silverado 3500HD / GMC Sierra 3500HD (Duramax) — Generally around 35,000 to 36,000 pounds with 5th-wheel/gooseneck setups
- RAM 3500 (6.7L Cummins) — Typically in the mid-30,000s for 5th-wheel/gooseneck towing
- Other heavy‑duty pickups in the same class — Most peak in the mid‑30,000s range for 5th-wheel/gooseneck hitch configurations
In practice, these figures are highly dependent on the exact drivetrain, axle configuration, cab/bed choice, available towing packages, and the weight distribution of the trailer. Real-world towing also hinges on payload capacity, braking, steering, and driving conditions. For a true 40,000-pound load, a pickup alone typically isn’t sufficient, and a larger vocational truck or tractor-trailer is usually required.
What it takes to tow 40,000 pounds
If your goal is to move a 40,000-pound trailer or load, the equipment and setup differ markedly from standard pickup towing. The following considerations cover what professionals look for when addressing heavy loads.
- Appropriate heavy-duty hitching and trailer configuration (5th wheel or gooseneck with high-capacity brakes)
- Strong chassis and drivetrain capable of handling sustained high-torque, high-traction conditions
- Adequate payload capacity and weight distribution to prevent overloading the tow vehicle
- Advanced trailer braking systems and, often, integrated brake controller for the tow vehicle
- Compliance with regulatory requirements for heavy towing, including licensing, insurance, and braking tests
Bottom line: reaching a 40,000-pound towing rating typically requires a larger commercial platform rather than a standard consumer pickup. The numbers listed above reflect peak capacities for heavy-duty pickups under optimal conditions, not guaranteed performance in every scenario.
What are the practical alternatives if you truly need 40k towing capacity?
For loads that consistently approach or exceed 40,000 pounds, consider these pathways that move beyond the typical consumer pickup:
- Use a heavy-duty commercial truck or medium-duty truck designed for heavy trailers (class 6–8 trucks, such as vocational pickups or semi-tractor configurations)
- Rent or contract a specialized transportation service with the appropriate rig and permit to handle high-weight towing
- Evaluate a purpose-built trailer with professional towing equipment and a compliant powertrain on the vehicle side to ensure safe operation
These options reflect industry practice for heavyweight hauling, where safety, braking, steering, and legal compliance become critical at higher weights.
Bottom line
For street-legal pickups, the practical ceiling for rated towing is in the mid‑30,000s to about 37,000 pounds with the best 5th-wheel/gooseneck configurations, not 40,000. Reaching a true 40,000-pound tow requires a larger, commercially rated vehicle or specialized heavy-haul equipment rather than a standard consumer pickup.
Summary
In short, no current mainstream pickup can reliably tow 40,000 pounds by manufacturer ratings. If you need to move 40k, you’ll likely need a heavy-duty commercial truck or a specialized trucking solution, rather than a typical pickup truck. Always consult the exact towing specification for your chosen vehicle, the trailer’s weight and distribution, and the applicable safety and regulatory requirements before hauling at heavy weights.
What trucks can tow 40,000 lbs?
Ford. The 2025 Ford F-450 Super Duty is one of the most capable towing machines on the market, but only specific configurations can reach its maximum towing capacity. For 2025, Ford sells the F-450 XL Regular Cab model, which, when properly equipped, can tow up to 40,000 pounds with a gooseneck trailer.
What is the heaviest you can tow without a CDL?
If the tow vehicle does not have a manufacturer-assigned GCWR, a Class A CDL is required if the combined weight of the tow rig and trailer/load exceed 26,000 pounds AND the trailer's assigned GVWR is more than 10,000 pounds.
What is the towing capacity of the GMC 2500 vs 3500?
The GMC 3500 HD has a significantly higher towing capacity than the 2500 HD, reaching up to 36,000 pounds with a dual-rear-wheel (dually) setup and the diesel engine, while the 2500 HD maxes out around 22,500 pounds. The 3500 HD is better for extreme hauling needs like large commercial trailers, while the 2500 HD is more than capable for most heavy-duty tasks and common heavy loads like large RVs or boats.

GMC 2500 HD vs. 3500 HD Towing Capacity
| Feature | GMC 2500 HD | GMC 3500 HD |
|---|---|---|
| Maximum Towing Capacity | Up to ~22,500 lbs (with diesel engine and proper configuration) | Up to 36,000 lbs (with diesel engine and dual-rear-wheel setup) |
| Typical Use | Common heavy-duty tasks like large travel trailers and boats | Extreme hauling, commercial trailers, and large fifth-wheel RVs |
| Payload Capacity | Up to ~3,975 lbs | Up to ~7,290 lbs (with dually) |
| Suspension | Less stiff for a potentially smoother ride | Stiffer suspension designed for heavier loads |

Key differences
- Towing power: The 3500 HD is built for substantially heavier loads, with its highest capacity reaching nearly double that of the 2500 HD.
- Payload: The 3500 HD also has a higher payload capacity, meaning it can carry more weight in the truck bed.
- Configuration: The 3500 HD's highest towing capability comes with the option of dual rear wheels (dually), which provides greater stability under extreme loads.
- Ride quality: The 3500 HD's stiffer suspension, designed for heavy loads, can result in a firmer ride compared to the 2500 HD.
