I am finally getting around to work on this fridge build that I received from Todd last winter. I wanted some opinions on what to do about removing the insulation and piping. I have an old Pepsi fridge like you would see in the gas station that has a glass door. The inside is all metal and has metal racks so my question is do you think I need to to anything to it as far as trying to remove what ever is on the back side of that metal? I was going to remove the motor and everything I can from the bottom but as far as trying remove any piping or coils that run inside the smoker in the back should I even worry about them since they are inclosed in the smoker and the inside where my meat is going to be is all metal? This is what I am work with.
