OK, but, that does look like a yankee contraption, I mean, where the hell is the fire box????
I assume it is similar to the Weber Smokey Mountain, which is also an upright smoker. The coals are placed within a ring at the bottom of the smoker. The WSM also includes a water pan which helps moderate the heat and has two grates on which to place food.
The Green Egg is supposed to be a really good product, but is much different in design than most smokers. It’s pricey.
