Yes, as others have mentioned, best to leave running. I read somewhere that the ammonia is somewhat of a rust inhibitor. when you shut it off condensate can cause rust and when turned back on it breaks loose the rust and can clog up the works.
What is most detrimental and already mentioned is if the rv frig is left running but not in a level position. This can cause overheating and crystallization of the rust inhibitor which is not reversable and will require replacement of the unit. while moving there is no off level issues.
Absorption fridge coolant......Ammonia, Hydrogen gas, sodium chromate (rust inhibitor) and WATER
Sodium chromate will crystallize and plate out on tubing if coolant flow is disrupted and overheating occurs.
Sodium chromate prevents rust from the water in coolant.
Rust doesn't break loose and clog ......sodium chromate crystals forming cause the clogging.
And YES ....it is permanent plus accumulative
