Adding a Snow Plow or Similar Equipment Before installing a snow plow on the vehicle, here are some things you need to know: Notice: If your vehicle does not have the snow plow prep package, adding a plow can damage your vehicle, and the repairs would not be covered by warranty. Unless your vehicle was built to carry a snow plow, do not add one to your vehicle. If your vehicle has the snow plow prep package, called RPO VYU, then the payload your vehicle can carry will be reduced when a snow plow is installed. Your vehicle can be damaged if either the front or rear axle ratings or the Gross Vehicle Weight (GVW) are exceeded. Some vehicles are built with a special snow plow prep package, called RPO VYU. If your vehicle has this option, you can add a plow to it, provided certain weights, such as the weights on the vehicle's axles and the Gross Vehicle Weight (GVW), are not exceeded. The plow the vehicle can carry depends on many things, such as: . The options the vehicle came with, and the weight of those options. The weight and number of passengers you intend to carry. The weight of items added to the vehicle, like a tool box or truck cap. The total weight of any additional cargo you intend to carry. . . . Say, for example, you have a 318 kg (700 lb) snow plow. The total weight of all occupants and cargo inside the cab should not exceed 135 kg (300 lb). This means that you may only be able to carry one passenger. But, even this may be too much if you have got other equipment already adding to the weight of the vehicle. 5-41
