No, I've been going back and fourth (in my mind) with the design. One day I'm leaning going with the end of tank (round & smaller) , the next day I'm thinking of cutting it flat ways, much bigger and if I did that I'm going to make one side of the cooking grill removable to drop in a "flat top" or a disk for skillet type cooking. Then I'll get to thinking that it's a waste of my LP tank and the round bottom will be difficult to get a even coal bed from front to back for a bigger cook for more than just the 2 of us, that was the main reason behind this idea. My tank is what I think is called a 120 gallon, about 30"wide x 50" tall, a nice medium size for a smoker and perfect for one like stoveaclause , the OP . I'm not hurting for another cooker and have 4 different options now, so I'll wait until I decide what way to go.
