What is the design gross vehicle weight of a 1991 gmc vandura?

The design gross vehicle weight (GVWR) of a 1991 GMC Vandura varied depending on the specific model and configuration (wheelbase, engine, options). There's no single answer. To find the GVWR for a particular 1991 GMC Vandura, you need to:

* Check the Vehicle's Identification Plate (VIN Plate): This plate, usually located on the driver's side doorjamb, will list the GVWR.

* Consult the Owner's Manual: If you have the original owner's manual, it will specify the GVWR for that particular vehicle.

Without knowing the specific model and configuration of your 1991 GMC Vandura, it's impossible to give you a precise GVWR.
