I make my own charcoal with cherry/mulberry (personal use, much smaller scale in a 35 gallon drum. Mill slab, stuff I buck, but it works ?), I also cook with those and other fruitwoods like apple/pear/peach... Start a fire in the pit and after they burn down to coals throw a fat steak on. Throw some
wet chips in for smoke.

I can't do hickory though, gives me
terrible heartburn, don't know why but it does.
Larry, that was a cool link, thanks.
