OK. I've been pouring through all available data on my 1985 Pace Arrow G31 and I'm left with a couple questions. These might be make model specific so I hope there's another Pace Owner on here. There are two switches in the bathroom on the cabinet at toilet level. Any idea as to what they are supposed to do? Also instead of two six volt batteries powering the home amenities I have two twelve volts. Is that a problem?
