38firetruck , Thanks for the info . I had thought of the ramifications and additional costs of paying passengers . It can be done with out to much of a problem under a business format , but I would not consider it with just my regular truck insurance , that's a fast way to the Poor House ! Taking friends for a ride is one thing , taking Hordes of kids ( or vets ) is another matter . Not to mention the exposed tank edges have to be smooth as silk so no one can get a cut , plus a thousand and one - make it safe for the most clumsy idiot can't get hurt while riding on the truck ! Humm , maybe I'll just build a Giant wooden keg on the back and run bootleg whisky to Stovebolt events ! Can you just see me trying to fill a jug with a 400 gpm pump , it might be more fun than a parking lot of Old Bolters , even for this Temperant Old Goat . I'd even be a rather Popular fellow , lol .
