residential refrigerator vs rv gas/electric refrigerator?

From the viewpoint of rough road surface G-Force affects on RV refrigerator reliability ... probably absorption technology wins over compressor technology for least amount of moving parts. I have no "proof" with respect to refrigerator moving parts being bothered by G-Forces ... just thinking out loud about Murphy's law and other things.

However, Good Enough usually wins over Perfection when it comes to getting by in the short to medium term. :)
