Don't believe our Ram has anything equivalent to Ford's BCP.
The quick way to verify if you do or do not have that functionality built in, connect a voltmeter to the battery and start the engine. Leave the A/C and lights turned off. Check the voltage at the battery. It will probably be >14.0V. Let your vehicle idle for 5-10 minutes. Check the voltage. It will be close to 13.2V.
Now, turn on the A/C, fan on high and lights. The voltage at the battery will probably be higher and so will the idle speed.

Our plan is to accept whatever current we can safely and reliably get at an idle from our 220a alternator.
Nothing wrong with that
as long as you do not need a partially discharge RV battery to be fully recharged by the time you reach your destination.
Without a DC-DC charger, that just will not hgappen.
