I've made a lowboy version with 11" legs and that was fun, but it left me wondering about that 3/4-inch conduit in 120-inch lengths. 120 is divisible by 3, hm? That would make three legs of 40 inches each. What could possibly happen?

With this setup, the rim is 43 inches above the ground.

I teased a local fishing discussion board, how about setting this up in about 30 inches of water as a free-standing grill you could paddle up to?
