To find the GVWR for *your* specific 2013 Chevrolet Tahoe, you should check one of the following:
* The sticker on the driver's side doorjamb: This sticker lists important vehicle information, including the GVWR.
* Your owner's manual: The GVWR will be specified in the owner's manual.
* The Chevrolet website: While they may not list it directly for every configuration, you might find it in specifications for your specific model year and trim.
Without knowing the exact trim and configuration of your 2013 Tahoe, I cannot give you a precise GVWR.
