Working on 2022 3500HD gas. Truck was sold used to owner as having plow prep. It does not have the VYU RPO. It does have 220 amp alternator, 5600 front GVW, skid plates and I found while researching the vin "PV - UDU provisions rear camera prep, VYU provision snow plow". I have added a factory rear camera which works fine. What I need to know is what exactly may be missing to have snow plow prep as I will be installing a Fisher plow and electric sander on this truck. Also will be adding upfitter switches and a second battery Thank you.
