To find the GVWR for *your* 2013 Dodge Durango, you need to check one of the following:
* The sticker on the driver's side doorjamb: This sticker usually lists the GVWR along with other important weight information.
* Your owner's manual: The owner's manual will also specify the GVWR for your specific vehicle.
Without knowing the specific trim level and options of your 2013 Dodge Durango, I cannot provide the GVWR.
