I have the larger of the Leader bottling units that runs on propane. I believe it would hold close to 20 gallons full to the top. It comes with the filter basket insert and the valve, spout, and adjustable shelf to hold your bottles / jugs. I am asking $825 new ones are around $1100 or so. Used for a couple of years but I downgraded to a smaller one. Propane tank not included.
