Refrigerator leave on or off during non use times?

Yes, leaving the refer on stops the cooling unit from rusting out by keeping it warm and dry.

I have always stored our RV's at home so I leave shore power on to the refrigerator. Monday I pick up my new to me DP with a big frig and when talking to the guy at the RV shop he said he thought they lasted longer left on??

I don’t believe in running appliances when not in use and not regularly present.

We turn ours off. Saves power.

if you're on shore power then i'd leave it on...that's what we used to do.

It somewhat depends on how the tray under the freezer conducts itself. Mine tends to freeze up a bit after a few weeks, so I usually turn it off unless we are heading out soon.
