All of the older Dometic 3-way fridges I have seen use the same
electrical thermostat for both 120V and 12V operation. I would expect yours to be the same. The particular electricity source is switched before it gets to the thermostat. However, the RM190 uses a 95 watt heater according to the service manual, so it would take about 8 amps of current, meaning your
battery would run down quickly. I would only use it on 12 volt for short periods of time, or in situations where you can replenish the
battery, such as charging while driving.
