[Babyhuey]

I got a 250 gallon propane tank 88” x30” ,I want to make an insulated firebox ,but it’s my first build ,so any tips would be appreciated. Starting with the dimensions, and then how thick the walls should be for the ceramic insulation

I recommend the build calculator as well that @SmokinEdge recommended ... I used it for my build (in signature below) and it works great...
