What is the curb weight of a 72 passenger International school bus?

The weight listed on the data sticker on any vehicle is the Gross Vehicle Weight Rating--the maximum rated weight. This includes driver, passengers, fluids, cargo and tongue weight of a trailer--but not the axle weight of the trailer. A standard school bus will have around a 25,500# GVWR. The Curb Weight (full fluids, no driver, passengers or cargo) will be around 15,000#, give or take. The Curb Weight is not listed on the data sticker.
