Benefits of running a dual battery system:If you are someone who goes or is planning on going on 4x4 camping trips (overlanding), then you will need auxiliary power.

Running a second battery will ensure your Toyota Tundra has start-up power and that your fridge, lights, and other campsite accessories have constant power.
