As an FYI our first Biese we built for ourselves we found an inexpensive spun aluminum talk on line that was like 14” diameter and like 30” long. I think it held 12 or 14 gallons. It worked great for what we needed. We could ski and play almost all day and not need to refill. We had them weld an extra bump or two in it for another 20 bucks. It came with mounting straps as well. You can see that it still sat nice and low.
Correction, I think it was 12” x 30” which put it right around 14 gallons.
