To find the precise towing capacity for your specific 1999 Suburban 1500, you should:
* Check the sticker on the driver's side doorjamb: This sticker lists important information about your vehicle, including its towing capacity.
* Consult your owner's manual: The owner's manual will also specify the towing capacity based on your vehicle's configuration.
* Use the VIN: You can use your vehicle's VIN (Vehicle Identification Number) with online tools or at a Chevrolet dealership to get the exact specifications.
Without this information, any number given would be an unreliable estimate and potentially dangerous.
