How much does a single axle dump truck weight?

Assuming the question is in reference to a Class 7 single axle vehicle, which would be allowed 33,000 lbs. gross weight for interstate use and 35,000 lbs. gross weight for intrastate use in some states. Empty weights for this type of vehicle would typically be between 16,000 and 19,000 lbs., depending on the make, model, length of the frame, how much fuel is carried, the height of the dump bed walls, the material the dump body is made of, additional equipment, etc.
