I've never heard of any recommended precautions for turning off the propane when you leave. It's similar in principle to natural gas or propane feeding your house -- you don't turn the gas off there every time you leave.

Would it be safer to do that? Maybe, certainly if you have a leak anyway, in which case you definitely wouldn't want it on when you're there!

Some folks who are dry camping for extended periods run their fridge on propane, and so their propane has to stay on -- could be for weeks or months.
