Another thing that makes that design so good is that getting rings rolled in quantity is relatively inexpensive. You could get say 10ea. aluminum rings out of 1" square tubing, 8' OD (or whatever dia you wanted), cut them in half, weld or bolt them to the trailer frame, and your framework is done. You could get the angle for the edges rolled at the same time.
I guess you could use the same process to make a fiberglass mold.
