Welcome to the board. I have a Chargriller and I love it. The temp control is a breeze once when you learn all about this grill. I think it would be a shame to convert it, but if you must; here is a link to converting a horizontal smoker using a propane burner : http://gassmoker.com/Afterburner_H.htm
. I don’t know of anyway to convert it to use pellets. I have looked at the Traeger Grills and they look very nice and handy, but they cost more than I wanted to spend. I also have a gas smoker, and I use it when I smoke things overnight, and it does not require much attending to. When I smoke in my Chargriller using the side firebox, I only add coals once every 3-4 hours. The temp remains pretty constant, and it does not require much attending to as well. I hope you’d give it a chance before converting it.
