There is a plate just inside the door that gives you this specification from the manufacture. It takes into account the various options you vehicle has. Otherwise they will all be different. You can check local grain and feed stores. They sometimes have a scale for their trucks so they wont go out over weight. Same with recyclers. That is how they weigh for big suppliers. If you go in they will give you the weight to the pound.
