New 6V Batteries for Fanny the Motor Home

Got 2 new 6v batteries for the motor home Fanny. The old ones were all used up and would not hold a charge. Cost was $480 CAD, got a $40 rebate on the old batteries.

The motor home has 4 batteries. A 12v motor/ignition battery, a 12 volt  in RV underneath box (2nd ignition battery? and generator starter battery). 2 6volt RV interior power batteries combined to create 12volt.

These batteries will help with longer boon-docking in remote locals while shooting AMBROTOS KANATA. 

The complicated battery wire hookup. I need to do a better job marking what wire goes where!
