What's your goal?

An AD truck is never going to be as quiet inside as a new car. It won't even be as quiet inside as a '65 VW Beetle.

Your windows are likely going to be down when driving in the summer so that negates much of the sound deadening.

I think heat insulation should be your bigger concern which will have sound insulation as a benefit.

Firewall, floor, and ceiling for heat.

Put some HushMat / Dynamat squares on the back of the cab and inside of the doors to dampen vibrations.
