Expert Reply:
You need one of the Roadmaster Battery Disconnect with Switch Kit # RM93MR (which is specific for diesel models) per starting battery on your 2020 GMC Sierra 3500.
So if only one of the batteries is a starting battery then you only need one, but if both are starting then you'll need two.
