A folded offset with firebox behind the smoker chamber.
Firebox is big, will work with wood logs or charcoal.
Think a snake method would work with charcoal, pretty sure could get an overnite non-tended cook.
Fire box doubles as a medium size charcoal grill.
The smoker size is big enough for about 8 -10 butts , or 3 briskets or lots of chickens.
It fairly well built .....but constructed of 1/8 in steel
It the past the Old Country cooker were either 3/8 or 1/4 in steel.
It was $499, not cheap , but not $1500 either.
