Lol.....actually, (embarrassingly) I only brought up propane tanks, because I was told by another contractor that the pressure points were the same and never even thought to see if this is true. The main reason for the thought of the propane tank, was solely due to the dimension of the 100 pound canisters, which could be welded to the bottom (underneath) the box of my box truck, which would allow me to take my big compressor out from the inside, which would create more room. Thanks for the input.
