Bought a Char-Griller Duo and Side Fire Box. Replaces the old Kenmore gas grill that always had a burned out burner. Everything cooked on it was "blackened". The Duo is a gas grill, charcoal grill, and smoker, all in one unit. The best of three worlds! Only mod so far is an expanded metal fire box and turned the main grill charcoal pan upside down.. Plan to add the flex pipe to the stack to lower it to grate level and a deflector over the opening from the SFB to the grill body. It's ready to season. I seasoned the gas side and grilled some pork chops. Works great! Can't wait to smoke something. Oh yeah. I checked the accuracy of the two thermometers in the hoods, both are on the money! Amazing!
