Master Switches

[Scott Forman]

My coach has two two master cut-offs. One is under the dash by my
right knee when seated at the helm. I have heard this one mentioned
by others before. It cuts off almost all 12v supply to the coach. I
also have a second one, though, at the left front corner inside the
battery compartment. This one cuts off the few items that still
function with the other switch off, such as the digital clocks and
thermometer. A couple questions:

1) Is that second switch in the batt compartment factory, or was that
added?

2) When I store my coach, I keep it plugged in. It has been my habit
to have both these switches turned off during storage. From a
standpoint of protecting battery charge, is it best to have them both
off?

Thanks
