Leave Propane Bottle Valves Open?

[heyskipper]

Hi Everyone

We filled our two propane tanks yesterday on our new-to-us ’99 Safari 25 footer. The attendant who helped us told us to just leave the valves open on the tanks and manually switch them when one empties.

Question: What is the general wisdom on running with propane tank valves open?

I understand that if we run with the refrigerator running on gas, then yes, leave it open. But what about when we are just parking it between trips?

Seems to me the valves should be closed when not in use. That means I open only one valve on the tank in use, and the other is closed until I switch to it, etc. When I store the trailer I close all the valves, etc.

Advice?

Thanks,
