Yes, I am glad I have it. It is a Samsung RF24FSEDBSR 23 cu. ft. Counter Depth 4-Door. It works fabulously - normally zero and 37 degrees (freezer/fridge). Mine is very rarely without power as I have lots of solar and a big lithium battery (and inverter) - I boondock nearly all the time. The only times it is without power is when doing some sort of battery/electrical system maintenance. It stays cold during these short outages but, with the internal temperatures on the door, you can certainly seeing it slowly warming up. Purely a guess but I would think mine would have 4-5 hours before the freezer got up to near 32 degrees if the doors are kept closed. I would not recommend residential unless you always have hookups or are able to power it from the coach (solar, battery, generator).
