My low end MH does not have any electronic valves (the propane stove works when there is no electricity) but it still has the delay before the stove burner will ignite after not being used for a while. Could it be that the propane system is now deliberately designed to leak outside the house on concern that a regulator failure or leak could cause too high pressure on the low side - at the appliances? Perhaps the deliberate leak is a safety feature of the regulator. I know my regulator area sometimes has a faint smell of propane that I cannot detect by means of detergent bubbles. If so, no wonder the propane bottle enclosure must be ventilated.
Are you sure about that- unless you have a pilot type furnace and have to manually light the refrigerator, you have electrically operated valves. Water heaters are the only common pilot type appliances used these days.
The regulator should not leak *unless* there is a serious overpressure- it will vent in the case, but that is a sign it is bad. In normal use it should never vent. I would replace it, just as a matter of maintenance, if it's over 5 years old or so.
