Let me add, for people who didn't see the earlier emails, that, in spite of
the fact that this sounds like a loose interior part rattling around, it
seems to be coming from behind the bench seat (or underneath the bottom of
it?)  I have been driven around with me in the back of the van going through
the interior, and with the engine compartment open.  The noise isn't
accessible from the interior and isn't coming from the top of the engine
compartment.  In fact, it was harder to hear with the engine compartment
open because it didn't get much louder.
