Paul,

I think an inspection of the bags is a good investment of time, before you conclude anything.

I have had two air bag blowouts, both were due to exterior damage to the bag. One, hyd fluid from the rear slide had dripped on the bag for an extended period weakening the rubber. The second was taken out by a blown inner dual tire.

If the bags surface is heavily checked, or oozing bubbles when sprayed with soapy water then an all around replacement is called for. Other than that it's hard to put a time or mileage limit on them based on dozens of variables.

I not saying replace or don't replace. I am saying don't be terrified. Be informed.

If you do lose an airbag in the middle of who knows where, the suspension can be cribbed with wooden blocks in lieu of the air bag to get you to safety. The ride is rough, but I have done it, and so has one other guru. You do need at least one 20 ton bottle jack to get the coach off the tire though.
