Have Dometic chest type AC/DC unit in basement. Run it on AC when camped, DC while traveling. Works great. Can't hear it inside MH. When getting food in/out, if the unit is running, I can hear the fans but not really hear the compressor. If was replacement for MH fridge, I suppose you would be able to hear it, but I would not think it would be bothersome. DW runs a fan at night so I would not be able to hear the fridge. Since we have 120V about 99% of the time when camping, I will replace the propane fridge with a residential when it fails. Will run it from its own inverter/charger and batteries.
