To find the exact towing capacity for your specific 2004 Chevy Express van, you should:
* Check the sticker on the driver's side doorjamb: This sticker lists the vehicle's specifications, including towing capacity.
* Consult your owner's manual: The owner's manual will have detailed information about towing capacity and other relevant specifications.
* Look up the specifications online: Use the vehicle's VIN number or the specific trim level (e.g., 1500, 2500, 3500, engine size, 2WD/4WD) on a reliable automotive website like Edmunds, Kelley Blue Book, or the official Chevrolet website.
Without this specific information, any number I provide would be inaccurate and potentially dangerous. Always rely on the information provided by your vehicle's documentation.
