You should never rely solely on internet information for towing capacity. The most accurate information will be found on the:
* Sticker inside the driver's side doorjamb: This sticker will list the specific towing capacity for your *individual* truck.
* Owner's manual: This manual will also provide detailed information about towing capacities and safety guidelines.
Check these sources to determine the precise towing capacity of your specific 2003 Ford Ranger. Towing beyond the recommended capacity is dangerous and can damage your vehicle.
