I'm mid project on this right now. I'm using the butyl foil lined Raam Mat. I purchased the materials a couple of years when I had my Titan and never got around to installing it. I had purchased two 62 ft^2 rolls of the mat and 6 yards of their 1/8" closed cell foam. I saw that Raam now sells self adhesive closed cell foam, so I will probably end up using that rather than screwing with spray adhesive. So far I have used one complete roll of butyl mat doing the back wall, rear pillars, and entire floor of my regular cab. I'm sure the 100% coverage is overkill, but I've got plenty of material. I didn't do any closed cell foam under the floor carpet as I thought it might affect the fit.
There is a substantial difference with just the back wall and floor done. I haven't done the doors or roof yet. I'm planning on doing 100% coverage on the roof and inner/outer doors. I am going to make some panels to seal up the large openings in the inner doors, I haven't decided if they will be metal or plastic. I was thinking ABS plates would work and I'll use silicon to secure them. I have enough material that I'll probably do a layer of mat over those too.
I did score 2 boxes of the Dynamat hood liner for $10 each at Fry's Electronics. It is the 3/4" foam with foil liner. I used most of one box under the OEM liner of the hood. I'm going to see how much of it I can put in the roof. I figure the foam and foil will help insulate the roof from the scalding AZ sun. If I have any left I'll find a place for it.
I did some major audio upgrades with the first stage of sound deadening, so far so good.

I had used the asphalt based matting in my Bronco back in the late 1990's. I pulled the door panel last weekend and found most of it was peeled off, some had fallen into the bottom of the door.
As for the Dodge, we did the doors with the raammat butyl product this past weekend, I'm glad there are only 2 of them
as it took longer than I remember on my previous trucks. My wife was nice enough to help, and her small hands are great for getting inside the door. The outer door skins are probably 80% covered, leaving room at the bottom for drainage. The inner door panels are 95% covered with plates covering up the three large holes that let the noise in. I didn't get much time to drive the truck Sunday before leaving on a business trip, but the initial impression is less road noise and better midrange response from the speakers. We used about 12 ft^2 on each door. I took pictures, but I don't have them with me on my work computer.
I may go back in and add several layers of the closed cell 1/8" foam between the inner door and the door panel, but I ran out of time last weekend. I still need to do the roof and A pillars, and if I get brave I'll do some work behind the dash.
