Our new Outback has a battery disconnect switch. It is inside and has the red key type that has off at 12 o'clock position and on at 3 o'clock position. When you are connected to shore power at a site or home when you are winterized do you have the key on or off. When travelling down the road should the key be turned off. Also when dry camping on or off. The manuals that came with the TT has no info on the switch at all on how to use it. I google it and get different answers. Thanks for any info.
