Full or empty ? Whether in a garage/house or an outside shed.
I tend to think that more gas = less air for condensation / moisture accumulation.... A piece of plastic under the cap to minimize this ?
Last year I filled the SS tank a bit too high and, at one point, raised the heat in the generally unheated room and the gas expanded and ran out the top...

We get horrible conditions where it's cold and damp and then the temp rises and condensation forms on every cold surface. It breaks my heart. Maybe a dry tank with the top sealed to keep most air out is best ?

Man that's a great question...

I tend to empty the tanks when stuff is going to sit, but my herd is in a climate controlled storage space.

I think filling the tanks in your situation is the right call. Depending on how big your shed/garage is...you could use a few calcium chloride absorbers to reduce moisture, but you would have to change them out every couple weeks for sure.

I used these at my old garage to combat gulf humidity as the old space wasn't insulated. They certainly helped in that regard, but may have a tougher time managing condensation caused by those big temperature swings. FWIW

Adding to Bird's:
Cover them with old blankets/sheets that breathe, and put this underneath.
