Hey all! I just got a vertical propane smoker and am set to smoke some pork and a whole chicken. Any tips for the first time smoker would be great. (Smoking basics that I need to know). I also have a couple of questions: - How often does the water need to be refilled and how often to change the wood chips? - Is it a good idea to put foil under the meat to help reduce the mess or does that interfere with the cooking? - What is the average cooking time for a 3-5 lb. pork butt and for a medium size whole chicken? - Should sauce/rub be reapplied during the cook? Thanks again for any help. I hope I don't sound like too much of a rube.
