Have a large BGE, here is the setup:
platesetter legs down, a few 1" thick half-bricks as spacers, and then the pizza stone
filled up the firebox with a combo of royal oak and full circle lump
lit the charcoal using a paper towel with some olive oil on it
the egg got up to about 850 and I let it heat for about 45 minutes
When the pizza went on the dome was down to about 700
Did three pizza's in all but did not take pictures of all of them. Turned out pretty good.
Roughly 4-5 minutes on the stone for each one. Each pizza took a little longer as the temp went down slightly with each pizza.
