I have the same noise. It happens from time to time when I stop from a slow speed suddenly. Sounds like something that is loose settling forward(and no there is not anything in the bed to make the noise).

i use to have a 98 that did the same thing...took it in and the dealer said this was normal ...it was something in the drivetrain...cant remember what it was though...but they told me not to worry..

Check your spare tire and shocks to make sure they are tight.

Mine does it once in awhile, most of the time its your locking diff engaging, it disengages at 25 mph and faster so what your prob hearing is the clutch packs engaging making the thump feel.
