Welcome to the Obsession! Nice pics of the uncrating. Excellent choice in color, too!
I had my deck rebuilt just before I got my KK (still had the old POSK), and did 2 things specifically for it - the joists in that part of the grill are on 8" centers (code is 12"), and the deck boards are ironwood, which won't burn. A necessity, since the rest of the decking is TREX.
