MO you could just take out that aux battery and anything to do with it, and not miss it at all.
It is a shorter distance inside the Class C from starting battery to house batts than from truck battery to trailer batts via 7-pin.
Yup... Just have to remove wire from terminal stud, and add 40 amp fuse in empty slot so 7 pin runs off starting battery...
Another crazy thing is the placement of the aux batt.. Its right at the cowl lip. When it rains it floods the top of the battery. ( GM had all sealed batteries as OEM) Since I changed it to a FLA design it took me a while to figure it out..
So battery overfills. I put a makeshift lid/cover on that battery.
So If GM guys have that set up or even dual start batterys and wonder why that battery is spitting acid everywhere, thats why. Rain water...
