Air ride suspension questions

[uppster]

I bought a 71 Suburban that has a home made complete air ride suspension with front and back separate controls. I am having trouble adjusting it for a normal ride. 2nd is durability and reliability. When I complete the LS swap I will drive it everyday and on trips. I am contemplating removing it and going back to dropped spindles and coils. I know the basics, trucks have bags etc. But I would like to hear from actual users that have had them for a while. Thanks
