I've done a fair amount of research on sound deadening stuff, but I haven't used any yet.
From what I have gathered the second skin folks seem to have a good selection of heat and sound stuff, and supposedly good quality and price.

http://www.quietride.com/Perhaps learn from the quiet ride folks and use the second skin products?
For my truck I want to do all I reasonably can to make it quiet inside, yet still appear stock or at least clean and professional looking.
Any tips or ideas?
