We have our RV on a permanent site which we can visit any season. We leave the refer on MOST of the time. Right now, we just returned from 3 months out west and we emptied the refer and it is off in the permanent location. We chose to eat our unopened foods while at home and re stock soon.
Nothing better than not guessing just how long old food products have been sitting around.
NEVER had an issue with this refer (1 1/2 years) or previous, 2005 model.
Do whatever makes you happy. Everyone deserves to be happy.
ps....here is a tip. Put an ice cube in a plastic baggie in the freezer. If it deforms from melting, you know you have had an extended power outage. If that thing melts, get rid of the "frozen" food that may have spoiled.
