Congratulation to the OP for getting things to work!
The advice in the quote above is noteworthy. A regulator is a relatively inexpensive and easy part to replace before you find yourself in BFE. I would not rely on a 25 year old regulator and would replace it at my first opportunity. You will find lots of regulators in Airstream's inventory in JC when you attend Alumapalooza. Take the opportunity to make the switch there. Lots of fellow owners will be glad to lend a hand, tools and/or advice.
