A terrible rattleing

[kendallcschm]

My truck has this what sounds like hollow metal being dragged on pavement sound when I'm driving and i hear it better when I'm driving slow as the motors sound is louder than the noise at high speed.. any ideas.. its not a 911 urgent.. nut it is important to me that i get some kind of answer soon

Is it coming from the front, back?
Does it change with the speed of the truck or does it change with the engine RPM?
Does it make the noise more when going straight or when in turns?
What about when braking?

i can't tell front or back cause it only happens when moving.. i know its not engine cause the engine feels real strong.. i don't hear it more or less straight or turns.. but when i'm slowing down i hear it more.. it sounds like something is dragging on the ground right under the cab

EDIT: i checked and there is nothing hanging down underneath the truck
