All this talk about fancy sound and heat insulation products, I'm with Snowtoy, free to cheap carpet padding.

Carpet padding I installed 6 years ago solved my in cab heat problem on the FJ80 and the cab is much quieter.
And after submarining my 86 4Runner a few years back I also installed carpet padding in it with equally good results.

To each his own...just thought I would share
