So I'm getting a old fridge this weekend (free). My plan is to turn it into a smoker that can be used as a competition smoker, so it needs to be able to burn wood/charcoal. Seems like majority of the fridges I see are either propane or electric powered. So I'm looking for pictures/help from people that have converted fridges that burn wood/charcoal. What do you use for firboxes, what size fire boxes, how do they attach the fire boxes? Any help on where to start would be helpfull.
