Is it ok or is it boom a go go? I remember reading that a type of regulator can make it safer, but have forgot.
In the USA, some states have laws regarding driving with propane on. I am assuming that propex is the same or similar? A few years back, a large RV was parked at a diesel pump with several other rigs when a propane appliance malfunctioned and the results were indeed catastrophic. Several deaths occurred, a whole diesel island was lost as well, as some semi trailers and their cargoes. Needless to say, I don't drive with mine gas turned on. Peace, Don
