According to both factories a newer refrigerator would have to be run off level for a couple of weeks to do damage. My coach is a 1998. I have parked it off level for several hours at a time and have had no problems with it.
Lack of COOLANT FLOW causes OVERHEATING regardless if on electric element or propane flame
Overheating is due to off level operation causing lack of gravity flow of coolant.
Sodium Chromate turns to crystals when overheated...crystals plate out on inside of tubing causing obstruction in coolant flow which causes more overheating of coolant/restricted flow ...more crystals/more plating---repeat
Damage from off level operation/formation of crystals is accumulative and permanent
ARPrv Device is a 'real time' monitoring system
Constantly checks temps while operating and has shown that unsafe conditions (overheating) can occur in less then 20 minutes
Time has changed since the 90's (different production/materials used)
