Propane Odor

[NY_Dutch]

Hey pshipsey

This is not an uncommon occurrence with B and C class RVs.
Awesome that you ran the tests and no leaks detected.
Being that the LPG is stored in a “closed” compartment, when the regulator vent emits vapour it is faced with being contained, even though the compartment is vented and none will enter the coach.
So, while it stinks, good ol mercaptan, just don’t examine with an open flame, kind of like protocols at the gas pump.
You’re safe and can sleep well.
Safe travels!

There should be no propane odor escaping from the regulator. The vent only serves to allow atmospheric pressure to adjust to the sealed diaphragm. If there is any odor, the regulator is either faulty or has a leaking connection.
