I got my hands on a 60 gallon air compressor tank, the legs are pretty rusty, i was going to flip it over and mount it on my trailer with the top platform that the compressor would mount on. What i am trying to figure is were to put the fire box. It will be mounted at the rear of my trailer length wise, and it is a little over 5 feet long. Would putting the fire box under it in the middle be a bad thing? If there are any idea's and or pictures, that would be great.
