GMC Truck Towing Guide

If you’re in the market for a powerful, reliable truck that can handle everything from weekend trailers to commercial-grade equipment, GMC’s lineup has a solution for every kind of job. With four distinct models designed to tackle various levels of towing—from the midsize Canyon to the heavy-duty Sierra 3500 HD—understanding their differences in towing capacity, performance, and available trailering equipment is key to choosing the right truck.

At Jerry Seiner Buick GMC, we’re breaking down the towing capabilities of the 2025 GMC Canyon, Sierra 1500, Sierra EV Sierra 2500 HD, Sierra 3500 HD and Hummer EV to help you make the most informed decision.

GMC Canyon: Midsize Truck, Full-Size Attitude

The 2025 GMC Canyon is a compact truck with impressive towing strength, making it ideal for drivers who want capability without the size of a full-size pickup. Powered by a high-output 2.7L TurboMax engine producing 310 horsepower and 430 lb-ft of torque, the Canyon offers best-in-class performance in its category.

When properly equipped, the Canyon can tow up to 7,700 pounds, making it perfect for hauling small boats, ATVs, or lightweight trailers. However, in off-road-focused trims like the AT4X or AT4X AEV Edition, towing capacity drops slightly to around 6,000 pounds due to their specialized suspension setups.

The Canyon also comes with available trailering technologies like Hitch Guidance, a Trailer Brake Controller, and an available Hitch View camera to simplify the towing process. It’s an ideal choice for drivers who tow occasionally or prioritize everyday drivability with strong utility.

GMC Sierra 1500: Balanced Power and Practicality

The Sierra 1500 represents the heart of GMC’s full-size truck lineup. Available with multiple engine choices—including a 2.7L TurboMax, a 5.3L V8, a 6.2L V8, and the renowned 3.0L Duramax turbo-diesel—the Sierra 1500 is built to offer a perfect balance of towing capability, comfort, and technology.

When configured with the 3.0L Duramax diesel and the Max Trailering Package, the Sierra 1500 can tow up to 13,200 pounds. This makes it ideal for those hauling mid-size campers, boats, horse trailers, or heavy utility equipment. Even the 6.2L V8 gas engine offers up to 13,000 pounds of capacity, giving buyers plenty of flexibility.

With GMC’s ProGrade Trailering System, available in higher trims, the Sierra 1500 provides features like an in-vehicle trailering app, trailer light test, and real-time trailer diagnostics—all designed to improve towing safety and driver confidence. For drivers who need a full-size truck that can tow heavy but still feel refined during daily driving, the Sierra 1500 is a top pick.

GMC Sierra 2500 HD: Built for Heavy-Duty Demands

For those with larger towing needs, the 2025 GMC Sierra 2500 HD delivers serious muscle. With its choice between a 6.6L gasoline V8 and the 6.6L Duramax turbo-diesel, paired with an Allison® 10-speed transmission, the Sierra 2500 is built for hauling fifth-wheel trailers, equipment rigs, and other heavy loads.

When properly equipped, the Sierra 2500 HD can tow up to 22,390 pounds with a fifth-wheel/gooseneck setup, or around 18,700 pounds with conventional towing using the diesel powertrain. The gas-powered variant still pulls its weight with conventional towing capacities in the 14,500–17,200 pound range depending on configuration.

What separates the Sierra 2500 HD is its advanced trailering suite, including available Transparent Trailer View, 15-camera surround vision, and optional digital variable steering assist for improved trailer control. Its reinforced chassis and high payload capabilities make it an excellent choice for contractors, RV owners, and those regularly hauling heavy equipment.

GMC Sierra 3500 HD: Maximum Power and Performance

At the top of GMC’s towing pyramid sits the Sierra 3500 HD, a truck engineered to handle the most demanding loads. Available in single rear wheel (SRW) and dual rear wheel (DRW) configurations, the Sierra 3500 HD is equipped for serious commercial-grade towing.

With the 6.6L Duramax diesel engine, dual rear wheels, and a properly equipped gooseneck hitch, the Sierra 3500 HD can tow up to 36,000 pounds. Even with conventional towing, it can handle up to 20,000+ pounds, depending on the setup. This makes it ideal for industrial trailers, large RVs, and equipment haulers that require absolute capability.

The Sierra 3500 also offers the same suite of trailering technology found in the 2500 HD, along with options like power extendable towing mirrors, enhanced cooling systems, and HD rear vision cameras. For drivers who want the most capable GMC truck available, there’s no substitute.

GMC Sierra EV: All-Electric Power Meets Practical Towing

The 2025 GMC Sierra EV Denali Edition 1 represents a bold leap into the electric truck segment—without compromising GMC’s core values of strength and utility. Built on GM’s Ultium platform, the Sierra EV delivers exceptional performance and impressive towing capacity for an EV.

With up to 754 horsepower and 785 lb-ft of torque, the Sierra EV offers rapid acceleration and serious muscle. When properly equipped, it can tow up to 9,500 pounds, making it ideal for most mid-size trailers, campers, or recreational vehicles.

Where it truly stands out is in its standard 4-wheel steering, adaptive air suspension, and Super Cruise driver-assistance technology, which collectively provide an ultra-smooth towing experience. Additionally, features like Regen on Demand and One-Pedal Driving help drivers manage payload and trailer weight with ease and efficiency.

While it doesn’t match the raw pulling force of a Sierra HD diesel, the Sierra EV is a smart, sustainable alternative for those who tow occasionally and want luxury, technology, and capability in one electric package.

GMC Hummer EV Pickup: Revolutionary Off-Road Towing

The GMC Hummer EV Pickup may be better known for its off-road prowess and head-turning style, but it’s also a capable hauler. This all-electric supertruck offers up to 11,500 lb-ft of torque (measured at the wheels) and can tow up to 7,500 pounds, depending on configuration.

While that figure doesn’t rival the Sierra HD lineup, it’s more than enough for smaller travel trailers, powersport vehicles, or weekend adventure gear. The Hummer EV’s massive 205 kWh battery, Extract Mode, and CrabWalk 4-wheel steering give it versatility that traditional trucks simply can’t match—especially for towing through challenging terrain.

Drivers considering the Hummer EV are likely looking for a blend of performance, innovation, and off-road flexibility with moderate towing needs in mind.

How Do the EVs Compare to Traditional Trucks?

If maximum towing capacity is your priority—especially for fifth-wheel or gooseneck applications—the Sierra 2500 or 3500 HD remains unmatched. However, both the Sierra EV and Hummer EV offer more than enough capability for the majority of everyday drivers, especially those who value eco-conscious driving, luxury comfort, and state-of-the-art features.

EVs also offer lower operating costs, reduced maintenance, and a smooth, quiet towing experience. For local towing or regional travel with access to charging, these electric trucks are excellent alternatives to traditional gas and diesel models.
