This is one of my next projects -- i will have to look into the PPV and who knows what else. Fun part is setting up a ramp so i can get under safely.
Also -- have to love an industry (actually MFR) where you can ask the manufacturers for the schematics and they have them -- and provide them. If anyone knows of a link to the schematics, i would appreciate the link. Meanwhile, i will be searching then contacting.
Spartan , has been sending out schematics when asked , and always best to have schematics linked to your chassis serial number .

I have two sets of Spartan air system schematics , neither has a production date differences include one has manual air pressure gauges the other electronic .
Sounds like your chassis has an aux air tank dedicated to the rear suspension, that would extend the time for the rear suspension staying up.
