How to hook up RV Jumper Cables?

To hook up RV jumper cables, first ensure both vehicles are turned off. Connect one end of the positive (red) cable to the positive terminal of the dead battery, and the other end to the positive terminal of the working battery. Next, connect one end of the negative (black) cable to the negative terminal of the working battery, and the other end to a metal ground point on the RV with the dead battery, away from the battery itself. Finally, start the working vehicle, let it run for a few minutes, and then attempt to start the RV.
