Atwood helium fridges have a tilt monitor.....it will shut down fridge if off level
ARP makes a safety device that monitors overheating conditions and will shut down a fridge if off level (off level causes overheating issues)
Norcold and Dometic installed 'recall kits' to trip all DC power if overheating occurs.
Off level operation damage is accumulative/permanent (little bit of overheating/little bit of crystallizing/little bit of build up----each/every time. Even that 15-20 mins on side of road).
Reasonably Level is the key......
GO CAMPING!
