Tank full is O.K., but we shut it off and purge lines for winter. Climate's fairly mild here but we do get freezing weather and propane will/can freeze and crack lines and regulators, especially if it's not moving through them- just like water.

That's because in places like where you live you are not getting pure propane. It has other stuff mixed in. Also, you can get water in your propane lines. Because you are in a mild climate they don't worry about it out there. Here in MN it's a real drag when that happens. I heat my home with propane down to 25 below F. Trust me it propane doesn't freeze. (until apparently 40 below. I've just learned)
But, I have had moisture problems getting into my home tank and then the moisture freezes in the regulator. Sucks when I wake up in the middle of the night and it's 20 below outside and I find my house has fallen to cold temps because the stupid computerized furnace thinks it's not getting the propane fast enough and it shuts itself off on the safety. Then I have to run outside in my boxers to pour hot water in the regulator. I will never get propane from that company again. It's really, really, cold outside at those temps.
