Bill: I hate when this stuff happens. I would be taking a long look at how the bag could become overextended. That configuration is designed for the bottom end of the bag where it is embedded in the bottom plate to be pointing down. An overinflated bag will be pulled upwards against the rim of the bottom plate and puts mechanical stress on the joint in addition to the air pressure stress. I believe there should always be a downward fold this style airbag.

On my 77 coach all the tapered cones on the bottom were loose and never leaked. I replaced the bags because they were getting cracks in the rubber.
