Other items you mentioned such as toad charge line and fog lights should be drawing their 12V from the chassis battery, in my opinion. ... or as other here have previously indicated, use the chassis battery for chassis stuff and the house battery bank for house stuff.
ED, I agree with your first sentence, but why not go ahead and hook the toad charge and fogs to the "charger bank" (converter) as it is also charging when the engine is running and not to put more load on the chassis battery? If it's because the chassis is a easy switch 12V, I can easily install a solenoid for 12V switch. I also like to keep my inverter battery bank free cause that runs everything while boondocking and the converter bank is basically my back up.
Having said that, do I stand correct and ALL 12Volts regardless if switch or unswitch should go to my converter banks and not to the inverter bank or the chassis battery?? Thx
