    A friend on mine bought a 2006 Pete for his farm. Asked me to show him how to drop the air from the rear air bags. I looked truck from front to back and never did find a way to drop the air.
    The truck is owner op spec and I think it originally was a Canadian truck.
    Why would a truck not have an air drop or am I missing something?

    Should be a switch on the dash,unless they spec'd it without the suspension dump switch.Might have to add the dump valve and switch if he wants it.

    ^ this. My own 579 came without an air drop and i had to have it installed. But if you have one it should like a bit like this.
