I have had 20 pound tanks filled by 2 different suppliers. They were
always filled to 19 or 20 pounds.


How long ago? Newer tanks with an OPD will not work very well filled
that much.

The last time was after the May 2015 tornado (used propane for
generator). One of the tanks (the one that held 20 pounds) was a new one
I had just bought a few years ago. The other was a tank from Blue Rhino.
All definitely had OPD.
