To find the GVWR for a *specific* 2007 Chevrolet Tahoe, you need to check one of the following:
* The sticker inside the driver's side doorjamb: This sticker lists the vehicle's specifications, including the GVWR.
* The owner's manual: This manual will also specify the GVWR for your particular Tahoe.
* Your vehicle's title or registration: This might list the GVWR.
Without knowing the specific configuration of the 2007 Tahoe, it's impossible to give you a precise GVWR.
