Nicely built with heavy gauge steel and wide doors. Can pack 12 beer can chickens in there with no problem and still have room for ribs. I only offset smoke in this unit, and with the added help of high temp silicone during assembly this baby is air tight and holds temps real well. I built a burner box basket to aid in fire box air flow and to contain the charcoal better. I also made heat baffles for the cooking area which gives me excellent control of the cooking temps across the whole cooking surface. Most of these modifications can be found on YouTube and made with stuff you probably have around the garage and house. I would have no problem telling you to pick the Ok Joe Longhorn smoker as it's done me right. Good luck, enjoy, and KEEP ON BBQ'in
