I did the cab roof, All the floor, gas tank (in cab), rear cab area , both doors from the bottom access panels. It made a night and day difference! I have an original 6 volt AM radio, I can hear it unless I'm going over 45mph, then it's like whispering. Worth your time and money for sure. It keeps the heat in during winter and somewhat keeps the summer heat out. I used a roofing material (comes in a roll), NO odor. I got mine at a Lowes. I bought a small hard roller and it was super easy.
