I have several suppliers in my area.
Two of them are good so far. I have been alternating my fill ups between them trying to stay on good terms with them both and to support them. Never know when an emergancy will crop up.
Amerigas and Ferrell gas are some others around here but DO NOT DEAL with them as you know.
There is another place out of my delivery zone in Amish country. Troyer's he is VERY good to deal with on the pipeing and regulators and keeps them on hand. Many places won't sell you any parts for LP systems around here. They are trying to cover their rears in case someone blows theirselves up.
