It's well thought out. The floor of the cook box slants towards the front door for draining drippings. I chose to use a cookie sheet inside.
The stenciled KBQ letters on the side of the firebox reveals the inverted flame when the fan starts pulling.
The firebox comes with a cover for when you decide to pull in some dirty smoke. Yes you can control smoke intensity, go all clean smoke, do half and half or all dirty.
