I did a search on google regarding the odor when I bought mine and read the label on the stuff at either home depot or lowes, and both said something about the noxious fumes. Could have been hype though.
I'm putting the peel and stick stuff everywhere, on the floor pan, firewall, roof, behind the tank, inside the doors, etc... I'm also going to put some of the aluminum backed jute under the hood and on the firewall to reduce noise as much as possible inside my cab. I'm also using the aluminum backed jute with aluminum duct sealing tape to join the ends together and 3m sprayable adhesive on top of the peel and stick under the floor mat and in the roof. With two layers of insulation it should keep the cab quiet and keep the heat/cool inside the truck.
