Jonah wouldn't reorder this if… Choose a dedicated firebox to maintain steady 250°F temps without fighting wind or fuel fluctuations. The product photo shows the firebox size and vent placement you need to check.

The chore is maintaining a steady 250°F temperature in a backyard environment where wind and fuel fluctuations constantly threaten your smoke ring. You need a dedicated firebox that isolates the heat source from the cooking chamber so you are not constantly adjusting dampers to compensate for drafts.

Look at the product photo to verify the firebox is a separate, dedicated compartment rather than a top-mounted box. Check the vent placement and the size of the firebox relative to the cooking chamber to ensure it can hold a consistent fuel load without spiking the internal temperature.
