Dan,
I hear ya' about your truck being a daily driver. Mine's on the road year-round - even in our New England snows! The sound deadening has helped a lot. And carpeting isn't just for trailer queens! I just makes for a nicer ride all around and makes your ccokpit much more comfortable. If you choose to not install carpet, the suggestion about spraying on the bedliner may help. Otherwise using all of the other products probably won't work for you.
