This might be the most amazing and interesting comment I've ever seen. Thank you :-)

What you say makes good sense too since many RVs have propane refrigerators. I've long wondered how it works exactly. Probably time for a DuckDuckGo search.

Propane fridges actually burn the propane for heat, so it's not using it as a "refrigerant", just as a heat source.

Those commonly use ammonia and hydrogen as the actual refrigerant: https://en.wikipedia.org/wiki/Absorption_refrigerator
