I understand your confusion, but I agree with your idea. If any one changes a good air bag on your coach, please don't toss it. Sometimes these extra parts do act like lucky charms! I was given a used drive axle air spring by Ron Skeen, Guru member and thank you very much!, and it was invaluable in my search to find my air spring numbers. When I change my air springs I will save one and give the others to members who own similar coaches.
