Hey guys, I have an 07 Tundra and I wanted a quiet ride. I laid down a layer of Dynamat Extreme and a layer of mass load vinyl from Second Skin (Luxury Liner Pro) on the entire floor and rear wall of the truck. It cut down the noise considerably. Now I can hear engine noise (coming through the fire wall in the front (which not much I can do about that) and exhaust/road noise coming through the doors. I think I can definitely do something with the doors. What material do you suggest to cover the doors? A layer of Dynamat Extreme? I read that Dynamat will cut down vibration, not so much with noise. The Mass Load Vinyl (Lux Liner Pro) is the stuffs for noise...however is too thick and I'm afraid the panel won't go back together. Any idea what's the best approach here? Thanks. john
