1995 Chevrolet P30 Air Bag Pressure

Big nonsense, CW replaced the blown airbag and corrected the problem.
How do you explain that.I still have the blown air bag to prove my point.

Try to make more sense in what you say to make yourself believable.

An Rv tech doesn't make an engineer.

I'm sorry but you're confused. Chevy put air bags inside the FRONT coils on the P-30 chassis to compensate for the load that the motorhome places on the front axle. When they manufactured the chassis they didn't know whether it was ultimately going to be a motorhome, bread truck or whatever. They are a band-aid of sorts - the right thing to do is to size the coil springs to the load on the front axle. Both my front bags are blown and the rig sits just fine. Handling is a bit sketchy - bags are on the to-do list. I've been driving it for years with no bags despite dire warnings in the manual that the front tires will shred pretty much immediately (didn't happen).

Rear bags, as mentioned, did not come from the factory. The factory setup on the P-30 was rear leaf springs. Nowhere to put bags even if you wanted to (EDIT: there are air bag helper spring kits, but not for the big truck chassis that I'm aware of). Some manufacturers and owners opted for aftermarket airbag systems that completely replaced the stock leaf springs. In this case, the airbag is taking the place of the spring rather than just providing a bit of help it as with the bags in the front coils. If a rig equipped with a rear air bag system blows, it will drop to the ground. I'm surprised you were able to drive yours. I have a slow leak in my right rear bag (Jet Ride air suspension) and when it leaks out completely (takes a few months in storage) it's sitting right down on the ground.

So this blown bag you have - is it a big black thing or a skinny red thing?
