Billed as the most efficient cooker on the market, this luxury charcoal grill is made with a two-layer insulating sandwich of refractory cements and an airtight lid seal. Its design reduces air flow, conserves fuel, and allows it to maintain a 230-degree temperature for up to 85 hours. The larger of the two models weighs 588 pounds—hefty, but not more than a code-built deck can hold. The glazed ceramic grills come in more than two dozen colors. Komodo Kamado. 424.270.1948.
