The ones I have seen that separated were in the area where the square bumper is welded to the frame support. The bumper metal is not thick enough to hole the weld and it tears away. The physics of the spare mounted directly over the bumper must not be as stressful on the welds.
If you use the forum search function, looking for rear mounted hitches, you will find numerous threads on this.
The Jayco cargo carrier option is expensive to add after delivery I hear.
I saw a Jayco owner last month, who had removed the square bumper and replaced it with a thicker square stock that was re-welded and braced with extra bracing and he was using a bolt on hitch mounted bike rack. Was very happy with it.
