Veddy eenteresting! Thanks for sharing. Good to know that there is another option. We may get to start the "Knocked off, knock off, smoker appreciation thread" if you keep finding all these cool toys.
If you Google Pit Barrel Cooker Forbes article In January 2019 it explains PBC departure from Amazon. While I don’t currently own a PBC I had one a lot of years. They’re awesome cookers. PBC taught me how to leave stuff alone. No gimmicks no gadgets. Light fire hang meat-eat. I was waiting on the PBC-Jr to go discounted. Then BHC came along for 45$. Haven’t used it yet.
