Airbags, dry-rot

[Bob Lawrence]

Hi guys,
Keep in mind that these are a bag within a bag.
The checked outer bag doesn't have anything to do with the inner one.
I do think it is a good idea to replace bags since they are old
anyways. Keep them as backups.
If you can only replace two, I would vote for the front one first.
