Still haven't made any modifications yet, but I might take a shot at making one of those elevated racks this weekend, with my (new to me) huge vice.
I find that with little or no effort on my part, my BBChef will hover very nicely between 205 and 220 F. I guess it's just how I build my fire. I only use charcoal to get it started, then it's all chucks and twigs of fruit wood... apple, cherry and pear, mostly, mixed 50/50 with oak chunks. Be judicious with chestnut, it packs a punch in smoke flavor.
Does anyone have any knowledge of smoking with Carolina Allspice? We all know that it's not really Allspice, or Pimento. It's known that it's berries are mildly toxic No one has said "For god's sake, NO!", or any king of negative response for that matter, but all the "Yeses" I get seem somewhat vague.
