Just an educated guess, but I would say, full. My reasoning for this comes from being a scuba diver, we are taught to never let our tanks go empty and/or be stored empty. By having gas under pressure in the tank it will prohibit moisture from getting in and causing corrosion to the inside of the tank. Of course the other resaon a diver does not want his/her tank to be empty is that is awfully hard to suck air from an empty tank 100ft below the surface.

Hi all

When it is time to store the Westy for Winter time. Is it better to have the
propane tank full or empty or it does not matter at all.?
