Any bed in any truck will have bounce, but some more than others. There is a video on youtube.com about this. Just do the search under bed bounce. I think the the foam object sandwiched between the spare tire and the frame is a great idea. An inexpensive possible solution to this problem. And for those who have yet to experience this, then try driving over rough parts of a freeway (in the fast lane in particular), or look in the rearview mirror when your going over a speed bump. Once you notice, it looks a little scary.
