one to the vehicle. If the vehicle

installed. The vehicle can be
damaged if either the front or rear
axle ratings or the Gross Vehicle

Some vehicles are built with a
special snow plow prep package,
called RPO VYU. If the 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
Rating (GVWR), are not exceeded.
