It depends...
On most Thor/Ford Class A gas rigs, there is a BIRD or BCC that connects the batteries at times to allow charging the coach batteries from alternator AND charging coach batteries from shore power/generator
On most Thor Class C rigs -Ford/Mercedes - the chassis battery is only charged by alternator as you stated.
In both cases, the batteries should be isolated when no power source is present.
Easy to verify with voltmeter.
The only thing consistent between our rigs is the Thor name... and the SOB owners even change that! Lol
