Thanks Steve,

This reminds me of another question.

Has anyone seen these go 20+ years?

Is there a recommended time for replacement?  If so, is this based on any science or just what feels good?

Our bags are 16 years old but look and work good.  Of course our tires were over 25 years old, looked and worked good but I still replaced those for safety reasons.

Thanks!!!

I replaced the bags on the 74' they appeared to be original and were holding air, but looked scary.. I'll look around to see if I have any receipt.  

Couldn't find receipt but the 74' had the same aux compressor setup and Ride-Well suspension.. The suspension shop I used In Mesa had no problems finding the replacement. Yours look great compared to the ones I replaced  the break drums are pretty scarce tho...
