That's a good point. Never asked about charging or if you have a gas motor with alternator to charge.
Isolation becomes key then if you are going to use those same two batteries w/ one as a cranking battery.

Having the 12 volt appliances running from the 24 v system will result in an uneven drain on the one battery shorting the life of that battery and the series. 24 volt systems like to have the batteries at the same state of charge. The TM might also pull the voltage way down on the 12v side under full power causing your FF to power down.
