Default Hardbody cab insulation material?

I recently picked up a 1997 Hardbody that I'm building as a daily driver. I don't plan to do anything too fancy audio wise, but I am planning to put a head unit and replace the factory speakers with mid-range aftermarkets. The main upgrade I want to invest in is insulation and sound deadening. These trucks are basically tin cans so I'm thinking proper insulation on the cab walls, roof, floor, and doors will make it a far more enjoyable vehicle for commuting whether I have music on or not. Does anyone know of a good all-around insulation material that helps with vibration damping, road noise blocking, and thermal insulation? I'm especially looking for thermal and road noise isolation because I live in an extreme climate, so I'm thinking Dynamat-type products may not cut it on their own.

Noico 80 mill sound deadening from amazon. 36 sqft for $65. I did almost everwhere in my single cab and still had some left over. The doors and roof made a huge difference. Well worth the time and effort.

Most sound dediner is the same.

Doors will make the largest impact followed by the roof and floor.

I wonder if Nissan did changes to their sound dedining over the years. My truck is pretty quiet inside, not as quiet as my Audi where I can hardly hear my own horn but it's not bad.

I used Stinger Roadkill adhesive deadener all over the floors, doors, rear cab wall, and roof of my truck. Made a huge difference in the "tinny" noise. I also put Roadkill foam deadener all along the floor. That made an enormous difference in engine/road noise.

EDIT: I forgot, I also put thermal tape down first before putting the adhesive deadener down along the area the exhaust goes near and over the transmission tunnel. It might be more effective put underneath the cab rather than on the inside, but I didn't feel like trying to clean all that. https://www.amazon.com/gp/product/B0...e?ie=UTF8&th=1
