I have never heard of this one. I've had LP tanks sit both full and not so full during freezing winters for the past 40 years and never noticed a thing.
I just leave it as it is when it comes time to winterize. We have a wood stove so if the power fails, which it sometimes does, we just throw more wood in the stove. I can't imagine staying in the MH when it is below zero and depending on the furnace for heat. The battery would die before the MH got warm.

The only concern with Propane and cold temperatures is, with the 'new' OPD valves on the portable tanks. I seem to be a magnet for valves that don't want to flow when it's cold.
Maybe it's just in my head but I've had several 20#ers that wouldn't work in the cold. My bulk tank doesn't seem to mind. And my old 'illegal' valved tanks, work too. I've been saving the propane that is in tanks with the 'bad' valves for cold weather. Unfortunately I'm down to my last 20#er.
Guess i'll convert to 100#ers, or rely totally on the frame mounted permanent tank in the coach.

I believe the tanks with the "new" valves have a feature which causes them to shut-off in the event the valves are opened too fast. I think this is to stop flow in the event you have a broken or cut hose going to the LP appliance. You should be able to simple close the valve, disconnect the hose, let the tank sit for 15 minutes or so (allows the valve to internally equalize and then reconnect and use as normal. When opening the valve you should do it slowly to avoid the problem altogether. Additonally, if the hose is not fully and properly connected to the valve, no propane will flow from the tank even if the valve handle (service valve) is opened. I don't think it has anything to do with the temperature or your "magnetisim".
Portable tanks (ie 20#) and vehicle installed tank valves work differently. Mosture intrusion is not an issue with either type of tank as was explained in a few posts above by Starcraft.

I have had the portable tanks shut off on me if the valve is opened too quickly with the plumbing unpressurized. To rectify this, close the valve then pick up the tank and thump it on the ground vertically. This should reset the safety valve and you can then open the valve SLOWLY to get things flowing properly.

Last year we had maybe one hours notice that a huge forest fire was headed our way, and also headed towards the only road out! Threw stuff in TT, hooked up, and went like h#$$. You never know. We were lucky, fire was stopped about 1 mile from our house. We had no damage.
BUT
We stayed fairly safe and snug in a campground about 20 miles away. Many of our neighbors were sleeping on a floor in a downtown church. Nice of church to let them, but I prefer my RV.

I'm glad you have been successful. I've found the above to be true in the warmer weather. Not so much in the c c c coldl I'm not all that 'fit' to wrestle the 100#ers but I may, just to avoid being "safe". To me OPD is/was, a waste.
I'm still posing the question. If OPD is so good, safe and necessary, why do the 100#ers that contractors and construction folks use, NOT have them? Is it safer if most of them are handled by Commercial Gas Suppliers? Or was there another reason? Hmmm.
Since it does not seem to matter, then I would store with a full tank! That way next spring you can head off on your new adventure without having to stop and fill the propane tank!
