Hi my name is Rich Day, I live in Gig Harbor, WA, I recently purchased a basic Char Broil propane smoker. I have never done this before and I have lots of questions! I would like to just try to smoke one of Costco's pork tenderloins , they are on the small side, I have read the other posts. I was curious about the time it would take to do a small tenderloin, I figure maybe about 2 hours? Is that about right? What is the best thermometer to get for a propane smoker, I looked on Amazon and found several.
