I have no experience on a gas grill,Dameon . But I smoke on a gas fired smoker. I slow smoke my meats at 250* for a min. of 4hrs and then wrap in foil and cook at 350 for 2-4 hrs ,checking for doneness till tender. seasoning with generic 'brisket dry rub ' ,I make my own now by the way pm me and I'll send ya the ing recipe . all are availible in large quantity bottles and WAY cheaper that way to make it .
