Thanks Dragon, I agree. I think this is doable, and if not then I will have failed in style, but I think it will work. Here is a picture of the two tanks that I have. I will admit I have been walking in the clouds a bit with all of this with some big dreams. I am starting to come back down to earth. I think what I will do is use part of one for the firebox on the other, and I like the idea of the center fired.
As a matter of fact I have just recently acquired some pictures that I will post on here when I get home. They are of a pit that is every bit 35 or 40 years old. It is a long tank that is center fired with the "double reverse" plate and the stack directly in the middle. I knew the man who built and cooked on this pit. He used it for years for large gatherings up until he passed away about 10 years ago. He loved the thing and it was built on the same principle that we are talking about, but done a lot of years ago. It has a great story behind it that I will share along with the picture.
These are mine and that is the trailer that it will live on.
