So, my parents and I both purchased a 2019 3121RL 20th Anniversary Edition. After a thorough inspection we have discovered that there is no way to turn the refrigerator off when connected to shore power. There is no off button in the refrigerator and there is no breaker to cut it off without turning the power off to half the coach. There is plenty room in the breaker box. Suggestion: put the fridge on its own breaker. You canít unplug the fridge easily. Sometimes you want to be in your 5er doing some work and donít need the fridge running. If you are disconnected from shore power, the inverter supplies power you the fridge. You can turn the inverter off and it cuts power to the fridge but as soon as you hook up shore power, it kicks back on.
