I want to use because 6 is better than 7.
I am wondering what the difference in the two are. Should I be worried with my BBQ grill outside that it is not an RV approved indoor regulator? Will I blow up when I BBQ?
Why would I, as a non-regulated human being, need to select one over the other?
What does one do that the other does not?
Is it worse to keep my fridge running on propane while driving with an rv regulator, or to have a BBq regulator on when parked (and not driving) or are they exactly equal in the Frowny Face world?
From what I can research is that the RV reg with the 2nd, big vent diaphragm, has a shut-off feature if there is an excessive flow, and a shut off feature if there is no flow.
