I picked up a big center cut boneless chuck roast this morning for my first try at a chuckie. I'm thinking of smoking overnight while sleeping. Plan to start and not check for 7/8 hours. With a roast this large at 225 to 250deg. I'm thinking I should be o.k. Anyone think it could be a problem? I'm using a uds that i've had no problems with maintaining tempature with. I have pictures of the before and will post Q-View when done.
