Another propane question?

[DQDick]

I can't answer the question about whether the regulator will revert back or not, although I suspect it might if left in the original position. I can give you a clue as to why temperature affects tanks so much. This article speaks to home propane tanks, but the principle is the same and to a certain extent exaggerated for us since our tanks are much smaller.
