For many years living on a sailboat in the Carib. we would transfer LPG from tank to tank by hoisting the full tank up in a tree , upside down and let the liquid flow into empty tank .
Exchange tanks , by law , must be under-filled , look it up .
Well, there is underfilled, and then there is
underfilled. The exchange tanks used to have about 18 lbs. of propane, but just a couple of years ago they started putting only 15 lbs. of propane in them but charging the same amount. That, to me, is an underfilled tank. Legality has nothing to do with it.
