I hope this is posted in the right place. I have an older Smokey Mountain Series charcoal smoker that I converted into an electric several years back. The element or controls went out last year and I am just now getting around to replacing them. The element and control I had in the smoker I took off a small electric smoker I bought from Wal-Mart for $28. They lasted for about three or four years, they are the exact same element and controls that Smokey Mountain Series sells as a replacement but for twice what I gave for the others. I really would like to have a better control and element. The smoker I have is the box type and is about 4 feet tall from the floor and the element I had just wouldn't heat well enough in the winter to get the temps up where I needed them. I want to insulate the smoker and cover the insulation with some aluminum I have left over from building a teardrop camper several years back. I really don't know what kind of insulation will work on it. I very seldom get the temps over 250-275 (that was in the Summer time) and not for long then. Does anyone have any suggestions what type of insulation will work and hold up? The way I smoke a butt is at 175-180 until the core hits 180 then crank the smoker up to 225-250 until the core temps hit 190. I take the butt off, wrap in a clean towel and place in a small cooler for about an hour or so. I smoke with hickory saw dust in a cast iron box that Lowe's sold for chips. I get the saw dust wet before putting in the smoker about a double hand full of dust is all I need for a good smoke. I also put 3 or 4 chunks of charcoal in to get the nice smoke ring.
