* Check the vehicle's sticker: Look for a sticker, usually located on the driver's side doorjamb or inside the glove compartment. This sticker will list the GVWR along with other important weight information.
* Consult the owner's manual: The owner's manual will also specify the GVWR for that specific vehicle.
* Use the VIN: With the Vehicle Identification Number (VIN), you can often find this information through online resources or by contacting a Chevrolet dealer.
Without knowing the specific configuration of the van, it's impossible to give you the precise GVWR.
