I've had one in the back right quarter panel that to this day I've been unable to track down. Very fustrating problem.
Its definitely driving me bonkers though, so I feel your pain.
I have this same clunk/rattle in my rear quarter. I actually gave up on trying to find it myself and took it to the stealership -wouldn't you know it, the truck was perfectly silent when we were driving it around. Mine rattles less when I have a full tank of gas, I'm starting to think that it's a loose gas tank strap or something.

I'll have to get my hands on a trunk monkey for some on-road diagnostics.
