If you are hearing rattles from things rubbing against each other, you need to get creative with weather stripping.

Dynamat (or any mat) is designed to convert sound vibration into heat. It is also designed to add weight to the surface you are trying to keep from resonating.

So no, you don't have to do the whole thing. But many do it all as a complete project. You can't have too much sound insulation and deading IMO.

its just the back where my bed and cab meets. that little crack there is what vibrates, nothing else
