Is there anyone out there that can help with ideas and designs for a trailer-type smoker for competitions and catering?
Here's a link to one guys solution
Also check the Q-talk index for a recent thread called smoker manufacturers. Theres links in that thread to all the mfgr's we could find. A lot of them offer trailer rigs. Check Backwoods, they make 2 sizes of catering trailers, enclosed with water systems.
