Spoolup, gonna take pics of the burner tomorrow. I like the smokebox/propane combination on this one. (See my post "My new toy" here in gadgets & gear from last weekfor picture.) I doubt I'll ever mess with competition... just need to do a lot of butts for different events.
Sid, It's piped from the tanks in the front to the burners in the back. Looks like 1/2" iron pipe.
