FWIW my fridge is never turned off except when at the dealer for repairs. It's plugged in at home and on gas when rolling. Back to electric at campsite. We keep drinks and water in it at home and when going on a trip load it the day before so everything cools down.
My understanding of the way the RV fridges work is the heat circulates an ammonium mixture to cool. If left off for an extended period of time it can settle out and cause problems. Years ago one of the fixes was the remove the fridge and turn it upside down for a while to get the mixture moving and it worked. For that reason all of my RV's are left on all the time.
The newer ones may be different but old habits die hard and (knock on wood) I've never had a fridge go out.
