With a long firebox measurement like that, I kinda figured that was the idea, with a quick slide in or foldable mod you could even make it dual zone.The firebox has a full length pull out coal/wood basket and the idea is you light one end and it burns to the other... the bottom front has DIAL INTAKES that can follow the fire as it moves from one end to the other... that gets fresh air right to where the fire is at that time... need a longer cook, just pull the basket out before the fire reaches the end and load it to go backwards.
