shutting down the Refrig or keep it On between trips

A shop that rebuilds them told me it's the people who turn them off and on that have the most problems with cracked/leaking units. I think they mentioned "weekend warriors". They believe the thermal stress of heating and cooling hurts them.
So I leave ours on all season. It's great to keep stuff in there and sometimes we have surprise trip and with the fridge ready to go we only have to load stuff we're going to consume.
