I have not, but Gizmo made a nice maze about 6" wide and 8" high. Or at least it was huge let's say. It held a lot of charcoal, and burned for quite a while.

I know of a guy who is a big time competition cook who does exactly what your asking about. He starts out with wood in his RF and during the overnight, loads the FB with tons of lump and changes the angle of his cooker. Since he cooks on a trailer rig, he lowers the tongue to where I would guess the cooker is at a 30 degree angle. It is the strangest thing I've ever seen. All I have say is this guy is a one man team with over 50 grand championships. It definitely works for him.
Thanks for the replies. Wonder why he angles the tongue down? Any specific way he loads the lump or just throws it in a "basket" and let adjust the air to where he knows will burn at his desired temp?
I'm sure the angle sorta snuffs out the fire, or at least doesn't allow it to run away. As we all know charcoal will burn much hotter than wood so the choking effect of the angle keeps the fire down a bit. Never did it but I might soon.

I'm gonna try the maze. Have a bunch of extra fire brick laying around, maybe i'll just line them up on the existing grate. Might not be the best, but this is more proof of concept. I'll post back in a few days after a trial run.
