According to your smoker's manufacturer's instructions, smoke the ribs concave side down for 2 hours and 45 minutes at 220 degrees F, using hickory wood.
After the first hour of smoking, begin to spray ribs with basting liquid every half hour until cook cycle is finished.
After the cook cycle, remove ribs, mop them with BBQ sauce and allow to rest.
In a large foil pan place cooking racks on the bottom and fill with water just below the rack line. Place the ribs so the bones are vertical and layer them in the pan. Do not allow the meat side of the ribs to touch the walls of the pan.
Place foil pan over medium-high heat and cook for 7 minutes. Remove ribs from the pan and place ribs on a medium-high grill and mop with BBQ sauce, turning frequently in order to not allow the sauce to burn.
