Factory air shock options

[davepl]

I have an NOS air shock system for my Custom Camper, but I'm wondering if, like the big B-Bodies, there was a system available from GM with a compressor and ride-height sensor.

It'd make a lot of sense for a tow vehicle. Currently I'd need to air it up at a gas station or before leaving home. But I've never seen an automatic load level setup on these trucks, so I don't know if it even existed beyond what I already have.
