I've got a chargriller that does just fine. But my wife wants the backyard fancied up, and wants to put a built in BBQ island on the side of the patio. Every BBQ island has gas grills, I"ve never seen one with a smoker. What I want to do is put a smoker in with a side fire box, and then a gas grill next to it The problem is I have never seen this done. Are there any smokers designed like this? I'm thinking I need an off the shelf smoker with a SFB, then build a metal tube (the red part of the diagram) and weld it to the sfb and smoker to get the heat/smoke to the smoking chamber. Anyone done this/seen this? Will it work?
