Exceeding the towing capacity can lead to serious consequences, including damage to your vehicle, reduced handling and stability, and increased risk of accidents. Several key terms are important to understand when discussing towing capacity. These include:

• Gross Vehicle Weight Rating (GVWR): The maximum allowable weight of the vehicle, including passengers, cargo, and fuel.
• Gross Combined Weight Rating (GCWR): The maximum allowable weight of the vehicle and the loaded trailer.
• Tongue Weight: The amount of weight the trailer exerts on the vehicle's hitch.
• Payload Capacity: The maximum weight of passengers, cargo, and optional equipment that the vehicle can carry.

Understanding these terms and their relationship to each other is crucial for safe towing. Always refer to your vehicle's owner's manual and the trailer's specifications to ensure you are within the specified limits. Proper weight distribution is also essential. Too much weight at the rear of the trailer can cause sway, while too much weight at the front can overload the vehicle's rear axle.
