A point that could possibly cause minor confusion: The Acme fittings
talked about are named somewhat confusingly.  They are called Acme
because their connections use a thread of the type called Acme,
27-degree sloped sides and flat top and bottom.   The RV Acme filling
valve is the same one used on stationary propane tanks for heating;
any propane  truck on the road should be able to fill you.  Willing
is a different question.
