Also get the adaptor hose to use a 20# propane bottle, the little bottles don't last very long.

This ^^^^^. I have both propane and white gas stoves. about 4 gal of gas sealed but it is mainly for the Coleman lantern for outdoor use. Propane does not go bad and I have some put away.

these guys will also sell an adapter to refill your little tanks off the big ones. Which is technically illegal to do I think

About $5 at Harbor Freight. Have one of those as well.....

The seal in the valve is susceptible to shrinkage in extreme cold temperatures, and can leak. Do not store indoors or near open flames such as pilot lights or sparks from power tools or you could end up having a disaster like the Challanger Space Shuttle.............
