Bueller is barfing up a lung, or so someone said. I think he is dying maybe, that's what I heard....
I have no idea what a S-10 is so I Googled some images. I assume yours is pretty much standard and is not a monster truck on 60" rubber or body kitted on 20" chrome spinners.
Is the rear bumper a seperate metal bumper or a moulded plastic one?
Is the bumper in the way of the body tilt?
A photo of the back end of the truck showing the bed, bumper and bumper brackets may help. Also where the bed is hinged to see how the back end of the bed moves relative to the chassis and bumper mounting.
