The man who can make ice is king.
Good news tonight. Today I hooked up 12 volts to the propane fridge I had bought then connected it to 120. It works. I am now fairly certain that it will work on propane which means I can make ice once it is installed.
I’ll be loading it up tomorrow morning to take out to the shack. Installation is going to be a major effort. I’m starting a projects page for it. Check it out for updates.
