I have owned 2 rigs with the battery disconnect switch. I have never turned the switch on either unit. I have done all kinds of electrical work on both units, on the 12 volt and 120 volt systems. I always disconnect the battery and unplug from shore power prier to doing any work. I can not think of any good reason why the switch is there in the first place since there are several items that are wired directly to the battery anyway. Maybe some think that by turning the switch off while there unit is in storage prevents the battery from draining down ? I have never had to store one and never will (or I will not camp anymore). All mine have stayed hooked up to shore power 24/7

I guess what I'm saying is I just don't get the need for anyone to ever change the position of that switch just because I have not had to do it.
