The big difference is propane is stored at around 100 PSI, CNG is more
like 2600-3000 PSI (both temperature dependent).
You also have a much higher energy density on propane. My guess is the
gas would be transported at the normal distribution pressures and
compressed to liquid at the fueling site.

I'll have to discuss this with the propane truck driver who fills our
buried tank. I don't know what state the gas is while it is in his
truck
and if there are changes made to it while it is being pumped into
our tank.

Propane is liquid in the tank, pretty much like the stuff you see in a
cigarette lighter.

I'll have to talk to the delivery guy. I've never actually watched him
top off the tank. I'm sure you're right, though.
LP = Liquid Petroleum. He's 100% correct.
