I am looking to install a dual battery setup so that I can run my ever growing number of accessories off one battery and not impact regular function of the Jeep. One of the things that I would like to do with the second battery is to have an auxiliary power source in the rear of my JKU. Specifically I would like to be able to install a fridge and possibly other electronics in the rear storage area and have them powered by the second battery thru some sort of power outlet. My main question is about what products are available (or home grown solutions) for installing a power outlet in the rear of a JKU? If anyone has some experience with products they can point me to I would appreciate it. Also if anyone has suggestions on a dual battery system as well that would be great. As ofd now I am leaning strongly towards the Genesis dual battery system.
