When we bought our 30 foot Keystone Cougar fifth wheel new it came with one preinstalled deep cycle battery rated at 85 ampere hours. Having camped for many years in a campervan with a similar sized coach battery, I knew that 85 AH capacity wasn’t going to cut it. We were headed off on a one-year journey and planned to do some off the grid dry camping.
I decided to increase our battery capacity and purchase a pair of six-volt golf cart batteries rated at 225 AH. I installed them alongside the original 12-volt deep cycle battery and included a switch so I could use them as separate banks. Since then I’ve used the pair of 6-volt batteries as our main boondocking power source with the single 12-volt battery as a backup source.
