If you T in on the low pressure side with a regulated line and do not use CHECK valves then unless the two regulators are EXACTLY the same pressure (And this is not even possible, even if you set them with very accurate test gear because as they cool, it will change, just a little) the lower pressure regulator will vent propane.
This is very likely what happened to the O/P
I have seen it happen, this is why I strongly recommend only the Original Genuine Article.
Oh, by the way. If you hook up an external tank.. odds are it will provide most of the gas during the day. (The Genuine article has Check valves in it).
The leak was not from the regulator. It was coming from the permanently mounted external supply hose into the storage bay. That bay absorbed at least 18 gallons of propane over a 10 day period and boy does it stink. I am just glad it was sitting on CW's lot away from any flame source or someone would be buying us a new motor coach.
By using a tee into the low pressure side with a regulated external source, I will be able to use the electric shut off valve and stop the flow from the main tank. Granted, this has not been done at this time and only should we need it in the future.
