Charlie Burke has written a very interesting article on existing gas bottles with conventional valves and their restrictions for the future. He does an excellent job at explaining the reasons for change and the schedule when the new OPD systems are required. The page with the info and a link to
Manchester Tanks is: http://www.airstreamcentral.com/techinfo/opd.html http://www.mantank.com/opd.htm

Thank you very much Charlie! You are a tremendous asset to the camping community!
