How much does a kenwoth t800 dump truck weigh?

Well, it's going to depend on wheelbase, what type of dump body you have, what your drivetrain consists of, etc. The last T800 tandem dumps I drove... with a steel split gate rock tub, C11 Cat engine, and 10 speed transmission, I had a tare of around 24,500. With a steel dirt box, C10 Cat engine, and 10 speed transmission, I had of around 22,500.
