Sigh...

The tank on your Westy is an ASTM tank, not a DOT tank.  As such it
uses a completely different set of regulations than your barbeque tank.
Additionally, there are no OPD devices manufactured for horizontal
tanks.  If a retailer refuses to fill it, find a retailer who knows the
rules. (Or go to the wholesaler.)

Last bullet:  # The 2001 edition of NFPA 58 modified requirements to
exempt horizontal cylinders manufactured before October 1, 1998, from
requiring OPDs.
