How much does a 24 passenger school bus weigh?

You'd probably be looking at between 16,000 - 19,000 lbs. empty, and most of them would be able to get by with a loaded gross vehicle weight of around 26,000 lbs or slightly less.

I have a 2002 Ford/Thomas bus that seats 24 passengers. The GVW from the manufacturer is rated at 14050.
