Propane Pigtail, NPT or flare?
From propane tank to the regulator I see two types of hoses. One is the NPT which I assumed the regulator too (1/4 inch threads, though that doesnt match the ruler) or 1/4 male flare or "inverted...

I would never use google, goodness with all the hate stemming from those people... there are many many other internet search options that do not hate our country.
so, problem solved, but why would a two tank system need to add an adapter and have a flare hose fitting vs having the NPT fitting? Both styles have the NPT on the regulator it seems, just that one has an adapter thread into the NPT so you can thread in a flare hose instead of threading an NPT hose directly in. What am I missing?
I have a very old reg that prob has the adapter in it.
This seems to be a left-over from ages past when the dual tanks used solid copper lines to go from tank to regulator instead of rubber hoses. These copper lines/tubes were flared so needed to have a flare adapter to fit into the NPT of the regulator.
It is not the regulator that is different, it is the pigtail.
The official description is that single tank systems use NPT and dual-tank systems use flare, but this is misleading... Both tank systems use NPT regulators but the dual-tank regulators have flare adapters already screwed into them so are called "flare" not NPT. You can unscrew those and use two NPT pigtails just the same. What am I missing (as in RV companies are stupid)?
All this sounds about right for the backwards thinking RV industry.
