Subscribed to this forum, and made my first UDF, cooked on it once and got the BBQ Smoker bug back. Was gonna scrap my worn out 20 year old oil drum pit, but after reading up on the RF's, I decided to recycle some of the old girl and re-animate her into a RF Smoker. Starting with a 110 gal. propane tank, and a fireplace insert. Got some pics, and will keep you-all updated. I will be sure to research this site whenever I need info. Thanks to all!
