I recently built this cage, sliders, and bumper for a friend. The cage will eventually be an exo, so even though it looks 'different' it won't affect strength. Even the way it is now with a full X-brace it would stand up to a good beating. The cage is tied to the frame, sliders welded on in 4 places, and the bumper and cage are tied together. Once he decides how he wants the spare tire mounted, the two bars in the back will be tied together to mount the spare.
