follow these guidelines:
Caution
Caution
If the vehicle does not have the snow
plow prep package, RPO VYU, adding a
plow can damage the vehicle, and the
repairs would not be covered by the
vehicle warranty. Unless the vehicle was
built to carry a snow plow, do not add
one to the vehicle. If the vehicle has RPO
VYU, then the payload the vehicle can
carry will be reduced when a snow plow
is installed. The vehicle can be damaged

many things, such as:
The options the vehicle came with, and
the weight of those options.
The weight and number of passengers to
be carried.
The weight of items added to the vehicle,
like a tool box or truck cap.
The total weight of any additional cargo
to be carried.
