I built a 33 gallon reverse flow last year. It works well but the small size creates some issues/limitations. I have acquired the tank for my next build. It is a 60 gallon. I was thinking of maybe doing an upright (to save space while not using). What are the disadvantages? I still want it to burn split wood and charcoal. Best to put the firebox off to the side or could I even put the fire box directly under the inverted compressor tank? I do realize the entire thing might be a little unstable so I would plan for that as well. Any links or advice for an upright compressor build? My other thought is just a traditional offset (not reverse flow), but I've kind of already done that.
