I smoked a 14 pound turkey for Thanksgiving, and another one for Christmas. I’ve been smoking turkeys on holidays for 20 years. The Weber held the heat for 6 hours! All I did was keep adding water and pecan chips.  Turkeys did not take six hours to cook, but I was curious to see how long how long it would hold the heat with one startup bag of charcoal. Weather was mild so I did not have to battle cold temperatures or rain. I’m very happy with it.
