RV Propane systems have safety features...
Your propane cylinders have a spring loaded shutoff valve inside the OPD valve
The BIG Green ACME Nut has to be attached to open that spring loaded valve otherwise no propane can flow,
The ACME nut has a thermal bushing that melts in high temps (Fire) and allows the spring loaded valve in OPD to close...no propane flow
The ACME Nut has an Excess Flow Trip check valve ....bust a line downstream and it trips limiting amount of propane that can flow
Propane system is only operated at 0.4 PSI you can whistle harder
then that
Propane air/fuel ratio is critical for propane to burn. (2.1 to 9.5 range)
Too much air.......No explosion
Too much fuel......No explosion
IF the propane system is NOT safe to use when in transit I would NOT trust it when I am stationary and asleep :S
