Depends. Just the steel weighs approximately two tons. The floor is usually 3/4" plywood with rubber covering, the windows are surprisingly heavy. The seats must be added in too. If you were looking at lifting a complete body including the firewall and windshield minus the frame, running gear and drivetrain, allow for about 3 tons.
The frame weighs about a ton, the rear axle and suspension about the same, wheels and tires are probably 200lbs each. The nose and core support are heavy too, the front axle with suspension and steering probably more than half a ton. A decent diesel engine would be 1500 lbs, a smaller one about 900 lbs, transmission with adapter plate from 350 to 700 lbs. Not hard to see how it quickly adds up to a bus that weighs around 8 or so tons.
Weight of the bus will depend on options and chassis used.
The gross vehicle weight for a 71 passenger school bus is 29,800lbs. The 71 passenger school bus can carry up to 48 students.
No way of answering without knowing make, model, passenger capacity, etc.
No way of answering without knowing drivetrain, chassis length, and configuration.
With or without your wife in the passenger seat?
The curb weight of a 65 passenger school bus is around 16,000 pounds. If the bus has luggage racks on top, it might weight about 300 pounds more.
1. @ 8,000 pounds cab and chassis weight single axle... 2. @ 10,000 pounds cab and chassis weight tandem axle...
FXDB 2014 Street Bob can carry passenger with weight of 7KG with hand carry while 20KG without hand carry.
2014 Dyna Street bob can carry passenger with weight of 7KG with hand carry while 20KG without hand carry.
IIRC, when I hauled loads of just three chassis from the Mexican border to Freightliner, the total shipping weight of just the three chassis was 16,000 lbs.
The calculation of what? The gross weight? The curb weight?
Motor home classification is determined by body type, not by weight (tare or gross). A Class A motorhome is simply a single piece body with a cab forward design... the chassis can range from anything from a Class 2 van chassis up to a Class 8 bus chassis.
