I am not familiar with your specific model Brinkman but if I were you I would do a search for mods using your model number in the search.I heard there were a few mods to do on my brinkmann. Of course the Home Depot review that posted what to do is deleted now! If anybody has any recommendations let me know!
That's a cool looking smoker. Keep us posted as to how the modifications go.It's a brinkmann 855 6100. So I searched it and came up with needing an SS WOK for my coal and sealing off the door and top.
