When I had my GMC pd4107 I could support the bus chassis by putting a hardwood block between the bumper rests and the frame. These are small posts that when the bus air bags are defleated the chassis would rest on them. I would raise the air bags as high as they would go, put a block under the bus and crawl under with my hardwood block and put them between the frame and these post, then lower the bus down on to them. The bus chassis could only drop lower if the tires went flat.

My question now is this possible with a Prevost? I have yet to get under my bus without a ramp.
