Rattling noise by the drivers side back door

[Candy]

Everytime i hit a bump or a slight jolt in movement in the truck, I hear a rattling noise at my backseat door behind the drivers seat. It sounds like the door is open and not closed all the way. My truck has never been in any accidents, there are no dings, dents, or anything with that door, but I hear a rattling noise and it's starting to piss me off cuz I can't find the problem. Does anyone have any suggestions?

do you have that privacy shade thing? slips my mind what its called, but it snaps into place and allows you to slide it over your cargo in order to hide from would be thieves. That can rattle.

Are the screws that hold the roof rack crossbars in place tight? I was on a trip from Ky to Pa and had one side come loose. It took me many miles to figure out what was causing the rattling. It sounded like it was coming from right behind me in the driver side back door.

You know what... now that I think about it, it may be the roof rack because I was at my friends house and I was looking at the truck from her second level, and one of the bars on the roof rack was not paralell like the others, having the appearance that it was loose and possibly sliding. But... I noticed that when I have passengers in the back sitting on that side, I don't hear the rattle anymore. So it's like maybe something is loose on the door. I've checked to see if maybe the seatbelt was slapping against anything and it's not. I thought it was the cargo cover at first too, but it's not. Dang, I hate when I can so noticably tell something is wrong but can't figure it out. I don't want to take it to the dealership for them to charge me an arm and a leg to check something so meanial out! Ya know!

Yep...that would be my guess too.
That's exactly what's happening in my '07 V8 Sport

Check to see if someone put a penny in the side door pockets. I had that happen to me before.
