I have a 10 year old Whirlpool fridge in mine and it still runs fine. Even on the modified sine wave inverter provided by the manufacturer. The inverter draws 22amps when the inverter is running. About the same DC draw as the camper fridge that I had in the previous camper that was only about 1/3 the size. I haven't had any troubles but with it but if you have a smaller inverter you might need to beware of the defroster or ice maker doing there things.
