I currently have a Brinkmann Smoke N Grill This one herehttp://www.brinkmann.net/Shop/Detail...ku=810-5301-C& It was given as a gift. I recently smoked a 8lb pork butt and 2 racks of ribs. It was very hard to maintain a constant temp and I had to keep adding coals every hour. Temp would not go above 230 and didnt stay there for long. It was a pain to add coals and the pan filled up quick so I had to take some out to add new ones. It took about 14 hours total everything came out great but I did end up putting the butt in the oven for 2 hours. I think the major problem was that it was 18 degrees outside. How often should I have to add coals? I know it depends on the air temp but it was such a pain in the a** to feed them through the little door. I had read alot on this site before smoking, thanks for all the good info.
