Any thoughts about filling up cylinders before storing trailer for the winter? Or, should one wait until spring to fill em’ when the LP will be fresh? Or, does it just not matter?
Remember an old auto shop teacher telling us that a full gas tank was better because it helped keep down condensation in the tank and hence, the fuel. Not sure if that was BS or just late sixties wisdom.
Propane has a long shelf life; it doesn't go bad with a few months. It might even last years. I say fill them up. Consider them a source of heat if your power goes out. Either with the RV heater, or with a small propane space heater.
Your shop teacher was correct. Gasoline tanks are vented to the outside. Water tends to accumulate inside the tank as temperatures rise and fall. Corrosion and fuel contamination occur. Oxygen is drawn in and damages the fuel.
Propane tanks are sealed and under pressure. Moisture only comes from the fuel itself. As far as I can tell, propane will not corrode the tank unless it is contaminated from the source.
Propane has an insanely long shelf life. I usually top my tanks up prior to storing for the winter, that way I have one less thing to worry about come spring.
We were cleaning out one of the old barns on the property prior to disassembling it. Found a couple of old (1950s) LP tanks that used to feed the cookstove in the old house. That house has been gone since 1968. The LP in the tanks was still good, used it to run my LP space heater.
