I get the impression that some of the units may not have two vents per battery box.
My 855S has a vent in the bottom of the battery box as well as in the top of the box.
The top vent is routed, as usual, to the front of the camper and the bottom is routed to the rear of the camper.
The concerns here are real. One other thing that concerns me is the electrical ground wire clamped to the propane line.
I did relocate the SurePower battery separator to the left of the power center in order to gain some space when removing the battery lid on the right hand battery.
