Research that tank size before you plunk some $$$ down on it. I just recently converted by Commercial Drivers License with Hazmat endorsement back to a regular DL.. a throwback from over 10 years ago when I did a side job driving trailers of compressed air. That qualified as a "hazardous material", and I seem to remember a limit of 55 gallons before specific regulations came to bear for the driver and the vehicle hauling the haz materials. If the tank is not connected to a vehicle's fuel system, then I believe the 55 gal limit applies... above which you need placards, commercial license (and hazmat endorsement.. even though its not commercial carriage) and you may even have insurance issues to deal with. Don't take my word for it.. do your own research. While DL's are state issues, the CDL is federally standardized and regulated.
 
I am well aware of some Usenet regulars who have their own transport systems rigged up... but I am not aware of the particulars..(size, etc)
 
I intend to put a 55 gal tank in the back of the pickup truck, toolbox style, and fill it within a day or so of going to the airport.. and then offloading into the plane as needed.

I aim to get a 100-gal or so tank on a utility trailer and use it for my plane(s) and loan it out to some of the locals who want to.  If I outgrow the trailer really dramatically, I'll buy an old fuel truck and just park it and fire it up when I need to dispense gas.

Sure 'nuff disappointing ... Jim S.
