My saying "I imagine the compressor runs a lot more to freeze the water" was a poor choice of words. I remember reading that using icemakers caused an increase in electric use. I did not know exactly why. Since Walter (38FLCamper) tested with the icemaker on, I wondered what a second test with the icemaker turned off would show.
Your post prompted me to search for info on icemaker power use.
I found this: "In tests of four different types of new refrigerators, National Institute of Standards and Technology (NIST) researchers found that ice makers increased rated energy consumption by 12 to 20 percent. About three-fourths of that additional energy cost is due to the electric heaters used to release the ice bits from the molds."
The above quote can be found here:

and more is here:
I am looking for info to help decide if it is practical to use one of the residential refrigerators offered by Cedar Creek when there is no electric hookup available and a generator is used to recharge the batteries.
If turning off the icemaker actually avoids a 12-20% power increase in real use, that would make a difference when running from an inverter and batteries.
