* Specific Engine and Transmission: A 2002 Silverado 2500 came with several engine options (gasoline and diesel). The diesel engine, particularly the Duramax, had significantly higher towing capacity than the gasoline options. The transmission also plays a role.
* Axle Ratio: The rear axle ratio affects towing capacity. Higher ratios (e.g., 4.10) allow for better towing performance than lower ratios.
* GVWR (Gross Vehicle Weight Rating): This is the maximum weight of the truck itself, including passengers, cargo, and fluids. Exceeding this is dangerous.
* GCWR (Gross Combined Weight Rating): This is the maximum weight of the truck *plus* the trailer *plus* its load. This is the most crucial number for gooseneck towing. This is usually found on a sticker inside the driver's side doorjamb.
* Payload Capacity: This is the maximum weight of cargo, passengers, and equipment you can add to the truck itself. This is independent of the trailer weight but vital.
Therefore, I cannot give you a definitive answer without knowing the specific configuration of your 2002 Chevrolet Silverado 2500.
To find the accurate towing capacity:
1. Check the sticker on the driver's side doorjamb: This sticker will list the GVWR and GCWR. The GCWR is the most important number for gooseneck towing.
2. Consult your owner's manual: The owner's manual will provide detailed specifications for your specific truck configuration, including towing capacities for different trailer types.
Only by checking these sources can you determine the safe and legal towing capacity for your particular 2002 Chevrolet Silverado 2500 with a gooseneck trailer. Never exceed the GCWR. Doing so is extremely dangerous and could lead to accidents, damage to your vehicle, and legal issues.
