Cost 55 dollars for 100 square feet. Similar to Dyromat. Put two layers in plus did the doors

I just put RAAMmat in Maych. Haven't gotten to drive it yet to see what difference it makes but it gets good
reviews and is waaay cheaper than Dynomat

Something else you can do is spray some under coating under the cab, in the fender wells, and then unside the doors, and back in the cab dorners in between the cab and fuel tank. Then you put duct tape over all the holes in the door under the door panels...that helps quite a bit.

Before you put in any mat material spray the cheap bed liner material in the doors,floor, behind the tank,behind the fire wall and under the head liner if you have one. Another place if you are really serious put a coat under the bed. Make sure you don't stop up the drain holes in the bottom of the doors.(one in the front and one in the rear)
$50.00 Goes a long way to totaly quiet down the road noise and if you put in the mats you won't hear anything if your window seal are in good shape.

You can buy dynamat at most stereo shops. Its real pricey but works amazingly well. One of the best things to do is make sure there arent any unwanted holes in the firewall or floor, leaking air makes alot more noise than youd think.
