I should clarify: I cut the dump bed into pieces because the previous owner had done a terrible job welding it together. It had to be replaced anyway. What's important are the hydraulic PTO and the linkages that tilt the bed. If everything is solid then go ahead and try to lift it straight off the frame... but the weight is going to be prohibitive and the size ungainly. A gantry crane or overhead winch hoist would be best if you've access to a well-equipped shop.
