What does Harsh ride means for the spring TSB

I have read several posts on this TSB and need more elaboration on what you guys mean by harsh ride?

 

When you load your bed up with roughly 500 lbs, it will bottom out when you hit bumps.

 

Does is start to hit the bump stop when driving over bumps?

 

Mine would bottom out with:
- minimal weight in the bed hitting little bumps or rough road, little potholes.
- speed bumps at low speed.
- carrying a couple of normal sized passengers in the back seat of my DC. (not supersized folks at all )
It was kinda embarassing with the passengers from work, they were like wth?

Talked to the dealer about the bottoming out/harsh ride and they replaced leaf pack/shocks & did an alignment. It does not bottom out anymore under those conditions. This was back in Oct 2007 & still exists today based on customer compliant & if you are within the 3/36 warranty.
