You cam burn wood in the CharGrliller Duo/Trio , either the charcoal side or side fire box. Need to watch size of wood.
These have been popular on this board since they came out. The Trio is just a Duo with a SFB on the charcoal half, but they're really nice rigs for the price (especially on sale!).
And yes, a CG will work as a stick burner as long as the fire doesn't get too hot. In fact I've done this using seasoned birch on the main charcoal grate (not the SFB) and the adjustable charcoal tray makes it work fairly well within limits (it isn't a Kalamazoo, after all). So the best thing to do is keep the lid open if you're grilling over wood, and keep the vents closed if the wood is in the SFB.
What I'd really like to see CG come up with is a gasser-Outlaw-SFB combo. I still love my Outlaw after 6 years of wild weather up here in Canada.
