Refrigerator question for you class A campers
We have had a Winnebago View class C for about 5 years, and a 5er for the decade before. We think at times of a larger class A for part timing in retirement. Many have commercial refrigerators. How do...

I have a RV type "Absorption cooling unit" (Refrigerator) this uses HEAT to Cool believe it or not so it can run on electricity (About 325 watts in my case which is not at all efficient) or Propane.. ONly moving parts are the gas valve and fluids inside the cooling unit (Gas and liquid) Just put a new cooling unit on it after 14 years and change last Oct. (OUCH).
Now it does use 12 volts for control and ignition but it can run a long time on a full tank of propane and a full battery bank.
I also have a 2nd Freezer. this is one of the high efficiency Compressor units (Engel) Both Dometic and Norcold have offerings in this class. Mine is a chest freezer and draws a great whomping 36 watts (3 amps at 12 volts) when running. I have over 500 amp hours of battery so you get the "how long". Even a single pair of GC-2 (220 amps hours) around 3-4 days
At one time both D and N had full size RV refrigerators using this technology but I'm finding them harder to track down now.. 35-45 watts the compressor is what I call a Danfoss class (look it up) may be a Danfoss or a competitor's but that class.
However when on the move.. I burn propane.
