Lifting and hauling a disassembled bed

[DarkFlounder]

70 8ft fleetside bed. Sides have been removed from the floor. Back panel is still attached to the floor.

How heavy are the component parts? Can they be lifted into the back of my 72 longbed fleetside without a crane?

I only need to haul them about 30 miles, and I can avoid highways the whole way if needed. So I'm not worried about strapping them down. However, I don't have many people around here to help me with heavy lifting.
