For those who are concerned about longevity of a residential fridge in an RV, we installed ours in '99 and it's still going strong today. I full time and have put over 220,000 miles on the coach since then. It does draw some amps (mine is about 3 AC amps while the compressor is running but it does not run all the time or even most of the time). Over night when no one opens a door I doubt it kicks in very much at all. In case the above poster was serious, NO, they do not run on propane but they run very well on an inverter. You just need enough battery capacity to handle the over night draw. For folks that do a lot of dry camping with a RR the addition of a good solar array will get the batteries back up to capacity pretty quickly but you may want or need to run the genny for an hour or two in the mornings. When driving, if your engine battery charges your house batteries (mine does) you will maintain or recharge the batteries as you drive so no battery capacity should be used during a long days drive.
I have not defrosted my freezer in the last 14 years. Anyone full-timing with a RV fridge able to say that? I also like the fact that I have no fire concerns and I have double the capacity of any RV fridge. I even have super filtered ice and water through the door so I don't have to buy bottled drinking/cooking/coffee water. I've got all I need and I don't have to open the door and lose my cooling.
Now, the additional reality is that my wife would NOT full time without one so an RV fridge was never an option for me.
