I have been researching auxiliary battery systems for my GU2.
I have cabling through to the rear that was installed by the previous owner.
He said he used to move the battery between there and his boat and van depending on what he needed.
I didn't get the battery with the vehicle.
I have heard that deep cycle batteries don't like NOT being used and will shorten their life quickly if not drained and re-charged regularly.
As I am likely to do weekends at best most of the year I am looking for suggestions as to the best battery to get.
I would like to run camp lights and maybe a small fridge, not much else although that may change after a few trips away.
I have all the wiring and even the wiring to a cig socket and Anderson plug that will become live once the battery is in place.

Maybe I just need an esky and ice and a battery lamp....
