The tow vehicle alternator and wiring and towed RV wiring first supply power to the RV house which includes an inverter for a res refer. Any excess power will charge the RV batteries.
The 12v power from my (dual, 220A + 157A) tow vehicle alternators is not routed in priority to my RV inverter. It goes directly to the RV vehicle running/brake lights, brakes and battery bank as the priority.
Also, with 377A alternator capability, even with wipers, heat/AC, and headlights, etc operating on the tow vehicle, we still have plenty of "excess power" to keep the RV bank charged for inverter use.
As I mentioned, in real-time use, our batteries never demonstrate any significant draw-down over an 8 - 10 hour driving period with at least 12.4 volts at the end of the day.
