This is my first time trying a reverse flow build. I have acquired an 80 gallon and a 25 gallon air tank. There dimensions are 20 x80 and 14x34.i am looking to use the smaller tank as a firebox. I know it will be slightly undersized. I'm looking for help on dimensions for cutting doors and other holes. I've used the calculator.. This is link to what I've got from it.. If anybody has time to look over it and give me some pointers it would be greatly appreciated.Link to BBQ Pit Calculator
