To find the GVWR for *your* specific truck, you should:
* Check the sticker on the driver's side doorjamb: This sticker lists important information including the GVWR.
* Consult your owner's manual: The owner's manual will also specify the GVWR.
Without knowing the exact configuration of your 2001 F-250 Super Cab 4x4, I cannot provide the GVWR.
