New to the forum and new bull owner. I have been cooking bbq for many years now, made customs stick burner smokers, just recently sold an insulated vertical stick burner and downsized to the RT-700 since I no longer cater. I have really enjoyed the pellet life and ease of operation. But I need a large shelf and really considering building one myself. Has anyone accomplished this successfully? And has anyone made any mods to their smoke box to have it as a cooking chamber option?
