A lot of brand new elbows and straight joint combiners for the classic gray tubing used in motor homes of that era. I was using these in a 1978 Revcon. Want to sell the lot, not just pieces. I think I also have a solid brass pressure regulator that I built.
A lot of 30 and 50 amp cords, adapters, should be everything you would ever need.
Make me a reasonable offer and I'll give you a fair price.
