My rear air bags deflate to fully down when the bus sits and isn't running, when the bus is running they fill up to full. IDK if there is any way of getting more upward travel. Unless I'm just confused. That happens once in a while.
Mine does the front first, but it's an Australian delivery Volvo. Have a look near your shock absorber on the rear, middle of the front axle, there will be a link rod to an arm and air lines to it.
That's the leveling valve. To adjust ride height adjust the link rod or move the valve body downwards
