What is claimed is: 1. A vehicle comprising: a frame structure; a dump bed; a ball joint assembly coupling the dump bed to the frame structure, the ball joint assembly comprising a ball and a receiver, the ball defining first and second grooves and comprising an external surface, the receiver comprising an internal surface, a portion of the internal surface of the receiver engaging a portion of the external surface of the ball, one of the ball and the receiver being attached to the frame structure, and the other of the ball and the receiver being attached to the dump bed; a first retaining element moveably coupled with the receiver and configured to selectively engage the first groove in the ball; a second retaining element moveably coupled with the receiver and configured to selectively engage the second groove in the ball; and an actuator coupled with each of the first and second retaining elements and configured to facilitate selective engagement of the first groove by the first retaining element and the second groove by the second retaining element. 2. The vehicle of claim 1 further comprising a third retaining element moveably coupled with the receiver, wherein the ball further defines a third groove, the third retaining element is configured to selectively engage the third groove, and the actuator is further coupled with the third retaining element and is further configured to facilitate selective engagement of the third groove by the third retaining element. 3. The vehicle of claim 2 wherein the ball is vertically bisected by first and second planes, the first and second planes orthogonally intersect one another, the first plane bisects each of the first and third grooves, and the second plane bisects the second groove. 4. The vehicle of claim 3 wherein the first groove comprises a first meridional slot, the second groove comprises a second meridional slot, and the third groove comprises a third meridional slot. 5. The vehicle of claim 3 wherein the first and third retaining elements comprise respective first and third pins that are each selectively moveable axially along a first axis. 6. The vehicle of claim 5 wherein the second retaining element comprises a second pin that is selectively moveable axially along a second axis that lies orthogonal to the first axis. 7. The vehicle of claim 5 wherein the receiver is pivotable about the first axis when the second retaining element is disengaged from the second groove. 8. The vehicle of claim 6 wherein the receiver is pivotable about the second axis when at least at least one of the first retaining element does not engage the first groove and the third retaining element does not engage the third groove. 9. The vehicle of claim 4 wherein the each of the first, second, and third meridional slots approach an intersection and comprises a respective end wall opposite the intersection, and each of the first, second, and third retaining elements are adjacent to a respective one of the respective end walls when the receiver is in a central position with respect to the ball. 10. The vehicle of claim 9 wherein the receiver further comprises a fixed pin, the fixed pin being received in the intersection when the receiver is in the central position. 11. The vehicle of claim 2 wherein each of the first, second, and third retaining elements is spring-biased to engage the respective first, second, and third grooves. 12. The vehicle of claim 2 wherein the actuator comprises a handle movable among a first position, a second position, and a third position, wherein the handle is coupled with each of the first retaining element, the second retaining element, and the third retaining element, and wherein the handle is configured to facilitate selective engagement of the first groove by the first retaining element, the second groove by the second retaining element, and the third groove by the third retaining element. 13. The vehicle of claim 12 further comprising a first linkage member, a second linkage member, and a third linkage member, wherein the first linkage member is coupled with the handle and the first retaining element, the second linkage member is coupled with the handle and the second retaining element, and the third linkage member is coupled with the handle and the third retaining element. 14. The vehicle of claim 13 wherein each of the first linkage member, the second linkage member, and the third linkage member comprises a respective Bowden-type cable, such that movement of the handle selectively applies tension to at least one of the Bowden-type cables and results in movement of at least one of the first retaining element, the second retaining element, and the third retaining element. 15. An apparatus for connecting a dump bed to a frame structure of a vehicle and facilitating tipping of the dump bed in a selected one of a plurality of directions from a load carrying position, the apparatus comprising: a ball joint assembly comprising a ball and a receiver, the ball defining first and second grooves and comprising an external surface, the receiver comprising an internal surface, a portion of the internal surface of the receiver engaging a portion of the external surface of the ball, one of the ball and the receiver being adapted to attach to a frame structure of a vehicle, and the other of the ball and the receiver being adapted to attach to a dump bed; a first retaining element moveably coupled with the receiver and configured to selectively engage the first groove in the ball; a second retaining element moveably coupled with the receiver and configured to selectively engage the second groove in the ball; and an actuator coupled with each of the first and second retaining elements and configured to facilitate selective engagement of the first groove by the first retaining element and the second groove by the second retaining element. 16. The apparatus of claim 15 further comprising a third retaining element moveably coupled with the receiver, wherein the ball further defines a third groove, the third retaining element is configured to selectively engage the third groove, and the actuator is further coupled with the third retaining element and is further configured to facilitate selective engagement of the third groove by the third retaining element. 17. The apparatus of claim 16 wherein the ball is vertically bisected by first and second planes, the first and second planes orthogonally intersect one another, the first plane bisects each of the first and third grooves, and the second plane bisects the second groove. 18. The apparatus of claim 16 wherein the actuator comprises a handle movable among a first position, a second position, and a third position, wherein the handle is coupled with each of the first retaining element, the second retaining element, and the third retaining element, and wherein the handle is configured to facilitate selective engagement of the first groove by the first retaining element, the second groove by the second retaining element, and the third groove by the third retaining element. 19. The apparatus of claim 18 further comprising a first linkage member, a second linkage member, and a third linkage member, wherein the first linkage member is coupled with the handle and the first retaining element, the second linkage member is coupled with the handle and the second retaining element, and the third linkage member is coupled with the handle and the third retaining element.
