Oh, man. Moving, especially combined with reducing, is a huge chore. I feel for ya. Good luck.
Since I guessed you were probably kinda busy, I took a few pictures from my bus this morning. It's a Blue Bird CSRE, so not "exactly" the same as yours and Vlad's, but the model year is close, GVW is the same, power train is nearly the same, so I figured maybe the front end will be the same or at least similar.
My tags say GVW 36,200 and front axle 13,200 pounds. When I weighed it after removing seats but before removing any floor or body metal, and probably with a full fuel tank and me in the driver seat, the front axle weighed 8,300 and the rear 15,200.
The shackle at the trailing end doesn't have a lot of height left to give, but I guess the air bags could be sized to deflect the spring down even farther than where the shackle bottoms out.
