I have a Jayco Penguin and have just about gotten used to it but there is still one thing I cant seem to get through my thick skull. Near the house battery there is a controller with a circular knob on it branded TMC. There are four positions - 1  -  1& 2  -  2  -  and  O which I assume is off. I was told about this when buying the van but with my brain have no recollection of what I was told. Is it for using two batteries maybe ? Can some kind nomad put me straight b

thanks Davo

Dual battery isolater/controller switch.
