How Much GMC Towing Capacity Do You Need?
Start with the trailer's actual loaded weight, then consider passengers, cargo, tongue weight, terrain and how often you tow.
Light to Moderate Towing
- Small utility trailers
- Personal watercraft
- Light landscaping equipment
- Small campers
- ATVs and recreational equipment
Depending on the loaded trailer weight, the GMC Canyon or Sierra 1500 can provide the capability needed for many recreational and work applications.
Heavy-Duty Towing
- Large travel trailers
- Large boats
- Heavy equipment trailers
- Fifth-wheel trailers
- Gooseneck trailers
The Sierra 2500 HD and 3500 HD are designed for drivers who regularly handle heavier trailers, equipment and payload demands.
Important GMC Towing Considerations
Maximum towing capacity is only one part of choosing a truck. Your complete truck-and-trailer combination should be evaluated before towing.
Before You Tow
- Know the loaded trailer weight: Include cargo, fuel, water, equipment and everything inside the trailer.
- Check payload: Passengers, luggage, accessories and trailer tongue weight count toward payload.
- Verify tongue weight: Keep tongue weight within the vehicle and hitch specifications.
- Use the correct hitch: Hitch and trailer equipment must be rated for the application.
- Check trailer brakes: Make sure the trailer brake system and controller are compatible and functioning properly.
Central Valley Towing
- Work trailers: Patterson and surrounding communities include agriculture, landscaping, construction and commercial applications.
- Recreation: Boats, campers, personal watercraft and recreational equipment can require very different configurations.
- Long-distance travel: Consider how often you tow between Patterson, Modesto, Tracy, Turlock, Manteca and surrounding areas.
- Heat, grades and highway travel: California heat, wind, mountain routes and long highway stretches can influence the truck and trailer setup that makes sense.
