If your truck runs on 12 volts but your RV has a 24-volt battery system, it is natural to wonder whether the two systems can safely work together. The question usually comes up when RV owners want to use a DC-to-DC converter to charge their RV battery bank while driving.
The good news is yes, a 12V truck can be connected to a 24V RV system through the right DC-to-DC charging setup.
