I have a 22.5. Last Thanksgiving I had to finish my turkey in the oven. Could not keep the temperature high enough. I am in New Jersey and a little worried about cold weather. I think I have learned a few things since last time and had some excellent suggestions from this forum.. So, I am thinking this year to fill the charcoal ring half-full with Kingsford Briquets, dump two chimneys of hot Briquets on top of them at the same time. Add a few chunks of cherry wood. Put on the bird. Should be OK for at least two hours... I will prop open the fire door if I have a problem... Also, I have some wood charcoal in reserve. What do you think?
