Im thinking about buying a Lang smoker. I have a few questions though: 1. Is the warming box heated from the firebox being mounted directly underneath and the metal plate(s) separating the firebox/warming box conducting heat? Or does smoke actually enter the warming chamber? 2. To follow up on question 1, I would like to cold and hot smoke sausage in the warming box. Have any of you guys tried this? What's the lowest temps you can get in the warming box? 3. I would like to mod the racks so I could have the tubing framed kind that slide out, how hard would this be to accomplish on this design? I would like to have a top and bottom slide out rack, I assume the Lang 84 and above have this already, correct? I have a bunch more questions rolling around up there but cant think of them as I write this thread. I've read the other threads about Langs and I appreciate everyone's input. Thank God for online forums!
