One of the reasons I run with 2 batteries in the trailer - furnace, water pump, fridge, slides, jacks and lights need DC power. When I dry camp for a weekend and need to run the furnace the extra battery comes in handy. Plus with out present trailer all of the slides are electric Vs hydraulic so I figured an extra battery would be good.
I replaced the original battery box with one that is designed for 2 batteries - NOCO HM426 Black Dual 6V Commercial Battery Box. I installed the vent from the old battery box onto the HM426. When I replace the 12 volt batteries I will replace them with 6 volt batteries.
