To find the GVWR for a specific 1989 Ford Econoline van, you need to:
* Find the vehicle's identification number (VIN). This is usually found on the driver's side dashboard.
* Use the VIN to look up the specifications. You can try using online resources like the Ford website (though older models may not have complete data online), or contacting a Ford dealership with the VIN. A vehicle history report from a service like Carfax or AutoCheck may also contain this information.
* Check the vehicle's sticker. The GVWR might be found on a sticker located inside the driver's side doorjamb or on the driver's side door itself.
Without the specific model and configuration, it's impossible to give a definitive answer to the gross weight.
