I created a second coal pan. That way I can get that one going, lift the cooker off of the original pan of coals and set it directly on the fresh pan of coals. But I usually get 5+ hours before I have to do this.
I use a modified minion. I place about 15 or so hot coals in a large juice can with both sides cut out. Pack around that with unlit charcoal and a few chunks of wood. Pull the juice can and whalla!
Hope this helps
