shutting down the Refrig or keep it On between trips

On shore power at home from 3-7 days before the first camping trip (usually March) until I winterize (usually in November). I generally don't have to defrost during camping season. I run it on propane during travel unless unlawful (some tunnels require no open flame).

Thats been the process for about 7 years now and has always worked for me. Just make sure your camper is level when your at home.
