Hushmat is the generally accepted method. Although for a super quiet cab, strip out the cab completely and put a few coats of Plasti-Dip on the metal surfaces THEN cover in Hushmat before relaying your carpet.
Plasti-Dip is basically synthetic rubber and not only has great sound deadening properties but also is a great insulator, making it much easier to heat and cool the cab. Of course, everyone in the restoration industry knows the value of Hushmat...

Anything with the typical aluminum backing and goopy butyl rubber will merely dampen vibrations and not really cut down on cabin sound. If you are looking for a quieter ride, try Dynaliner made by Dynamat. I used 1/4" on my Buick doors and wow, what a difference. I wish I had done that to my Ram.
I bought a couple of trunk rolls online for $40 each or something like that. 2 was plenty for the doors.
11102 Dynamat DYNALINER is what I bought.
1/4" is pretty thick and you will have to do a bit of trimming. Use 1/8" in tight places.

I've been doing alot of research, and I'm thinking about using the butyl backed stuff (which is a product called CLD: Constrained Layer Damping) in certain areas because it is a vibration stopper (like the transmission tunnel, around speaker locations in the doors...). Then I plan to use the foam stuff (like RAAMmat ensolite) in areas where high frequency sound gets in, as well as between panels that slap together (around the windshield, between dash panels...). I've used certain brand names here, but merely as an example, they are not necessarily the brand/product I will go with. Any have thoughts on this plan?
