I gave up finding one and had mine made at a local propane dealer.
Hey, do you know Wayne and Carolyn Kenner? He used to be the postman in Devils Lake, and she ran a child care. One of their daughters is looking for a vintage airstream, and her husband is an airframe mechanic.
The fittings on the main supply line are way oversized...5/8" ,so a replacement line will be very hard to find, reduce to 1/2" flare on both ends, regulator and copper tubing on coach and a replacement line will be available at most any RV facility.
