As Yeller states, I have a lot of this product in my Bronco trying to quiet it down and keep it cool since I don't have any HVAC and am in Texas.
I have two layers of Dynamat Extreme on firewall, floor and bulkhead, topped with one layer of 1/8" Dynaliner type foam (specific product I bought is no longer available but it's the same), one layer of Dynapad on the floor pans and around trans tunnel, and one layer of Second Skin jute thermal insulation on the seat platform. On top of this is mass backed carpet from Stock Interiors.
On the doors and half cab top I have one layer of Dynamat extreme and one layer of 1/8" Dynaliner. I don't use the heavier products on vertical or overhead panels.
Dynamat and dynaliner are both peel and stick products so easy to use. The Dynaliner I have just set in place. You can glue it but because I'm only using on flat surfaces it stays in place just fine. The jute insulation is just set in place as well. though you can glue it.
I can't attest to heat reduction yet because I just finished Bronco and haven't gone through a summer yet, but I've done all I can to combat it outside of adding AC. I had less of this material in my last Bronco and it worked so I think this will too. The cab is very solid feeling and quiet and air tight so the noise reduction properties are for sure there.
Outside of Dynamat products Second Skin Audio has several different products that work to counter noise and heat. I have more of their jute thermal insulation and also their luxury liner pro material that will go in my F250 along with Dynamat Extreme and Dynaliner. If nothing else give Second Skin a look for more ideas and explanations on what the various products do,

Here are the pictures that I do have.
it will make Shorty quieter than my F150 down the highway. I can handle the extra weigh dogging my stroker if I put a blower on it to help move the weight. lol
