Thanks for the links for the tank manufacturers. I called a local one I found on the net today, but they are not as professional as I would like, more of a fab shop. They were talking about schedule 40 pipe with caps welded on, that's about 3/8" wall. much to heavy to carry around on a truck. Tanks of the same size and pressure rating from big trucks have about 1/8" or less wall, that's what I want, just enough to be safe. I checked out the steel fab web site, it looks like they can do what I need. Now I just need to draw up an auto-cad drawing of the different tanks I need and get a quote from them and the others.
Yes, I will do some sort of round the country trip when done, the last one was so much fun I can't wait to do it again. Grigg
