weAve's the name building Jeeps is what I do. I've had a Char Grilled Duo for about two years now. Just recently got the Side Fire Box. Used to smoke on a small Brinkman Smoke n' Grill. Still not sure if I'm doing it right. Still trying to work out the kinks, so to speak. Any help with smoking on the Duo with the SFB would be greatly appreciated!!
