It takes 4-6 hours to bring a 10ish lb roast to room temperature. Stick a meat thermometer in the center if you don't believe me. I've done three this season on a Treager all were excellent. My method is start with room temp, smoke 2-3 hours, then cook at 225 for 2-3 hours, then crank to high heat (450ish) for 15-30 minutes, rest covered 15 minutes.
