The 20" RD Special Marshal is the most popular smoker in our lineup. It has the same dimensions as the 20" Marshal but comes standard with almost every factory installed accessory we offer! We've added a counterweight to help lighten the cooking chamber door. The sliding convection system and extra thermometer help regulate and monitor the temperature in the different cooking zones. Includes 20" wagon wheels for easy maneuvering and a heavy-duty charcoal grate that lasts for years. This could easily be the last smoker you ever purchase.
