plastic propane tanks

When the recall came out you were to have the cyl. empty and send it back to the mfg. Since they were so many mfg. could could not pay the
fgt. or place to put them. They closed the doors and went bankrupp.These tanks were popular with boat owners as well as rv's.
Last that I saw they are NOT to be USED or REFILLED by PROPANE
Dealers.Lots A luck in getting them filled.
