To find the GVWR for *your* specific 2003 Ford Expedition, you should:
* Check the sticker on the driver's side doorjamb: This sticker lists the GVWR along with other important weight information.
* Consult your owner's manual: The owner's manual will also specify the GVWR for your vehicle.
Without knowing the exact trim level and configuration of your 2003 Expedition, I cannot provide the GVWR.
