Installed the sound deadener in cab and lower the rear with lowering coils,Big difference. The floor cost me less than $100 and the lowering coils were $169. Pays to shop around.
Lowes Peel and seal. Did the whole cab for less than $100 compared to Dyamat $ 800. Stuff sticks great and no smell at all. A lot of hotrodders use it with great success. And to the stereo guys no I am not building a thumper box,sound proof and all. Just a driver.
