The picture of my bus on 6 stands is because I was supporting the suspension in the rear, not the frame. I wanted the little extra height the air bags gave when they where overinflated.
I did measure the bus with tires on and the level low system as high as possible yesterday. The front is from the ground up to the bottom of the tow hook plates, 11.5"
The rear is behind the tag axle just in front of the transmission, there is a cross bar that mount to the frame and runs from side to side, from the ground up to the bottom of that bar is 12.5"
This is a 2000 XLII 45' shell.
