If you watch the video, during the biscuit test, you can see the bottom plate that forces all the heat to the door (side farthest from fire box) for a nice reverse flow design, love that pit.
@ 7:42 of the video, when he pulls the bottom rack all the way out, you can clearly see the R/F plate on the bottom. Beautiful design.
