The LWS that is most little-guy-friendly in my area is a GTS-Welco which is part-owned by Praxair. The proprietor absolutely refuses to let anyone stuff cylinders into a car cab or trunk. Can't blame him really. Some ambo-chaser from Dewey Shaftem & Howe will try to make a case if it leaks and asphyxiates the one-year old kid left in the car on a 95 degree day or slides around and busts up the Waterford crystal or makes a fireball when the door switch sparks.
A few years ago an acetylene tank leaked in a Mercedes trunk and totaled the car. BATF, FBI, DHS and the Klingons investigated a "possible" terrorist incident until they found out it was common stupidity.
With fuel gas the threat of death is real based on results. I use my F-150 instead of the ricebox grocery chaser but no one had to convince me it was a good idea. My personal goal for leaving this life is to be shot by a jealous husband when I'm 99 and so far it's going to plan.....
