It's more important that you identify how your isolator works. Your fridge should be wired to your aux battery which should be isolated from your main battery when your car is not running. This means that when you leave your fridge running overnight, it will only drain power from your second battery, leaving the primary battery with full power to start your 100 series in the morning. Then when you fire up your car, it will start recharging both batteries. You won’t need a 3rd battery, although you might want to consider an upgraded unit.
