after debating for a while between a KJ III and Louisiana grill, I bought the Louisiana grill from Costco given the big price difference. I created an island around it and my grill is enclosed inside (see photo). I did leave a 8" x 20" opening in the front for air intake. I am not sure how hot the outside of the grill gets and if I should insulate the grill with ceramic insulation etc. Directly or the walls of the enclosure
