Indirect cooking is the way to go with that. leave firebox empty and start a small minion fire in the cooker area closest to firebox. You still control air by the firebox intakes, but all the fuel is in the main box.
This setup makes for a pretty efficient cooker. Ribs, chicken, you name it, it'll do it.. but you aren't wasting energy trying to heat up the outside firebox, then push that heat through the cooking chamber.
