Here are a few pictures of the cold smoke box I built out of a small trunk. I attach this to the smoke stack of my Traeger Lil Tex using 8' of dryer vent. The temp of the smoke has never exceeded 90 degrees F. I have two racks that rest on dowels and there is room in the box for another pair of dowels for a third rack. I attached an old meat locker thermometer to the door and routed the probe to the smoke inlet port.
