There's an off option? Just kidding....... But, we leave ours on, to keep the fridge stuff frozen hard, (ice cream, meat, pizza). Unless if there is a legal restriction along a travel route, it stays on.
This is completely contrary to my old practices when pulling a PopUp with a 3-way refrigerator. I would always insist that the propane be shut off when travelling. But, the 3-way fridge could run on 12v while in transit, keeping everything cold.
Newfangled large absorption refrigerators used in motorhomes are only designed as 2-way, propane or AC. So, I choose to use propane while in transit. Of course, if it's really hot and muggy outside, I'll run the genny to fire up the A/C, which will automatically power the refrigerator also. But the propane valve at the tank is still on.
