cheapest way to make my truck quieter?

[Skunksmash]

I have used peal and seal on my truck, but I took it off. Actual sound deadener works a whole lot better. Such as the B-quiet I mentioned. Any buytl based rubber with aluminum backing. I noticed a huge difference in sound reduction from the peel and seal and the B-quiet. But to anwser the OP, there really isn't a "cheap" way out on this one. I've calculated it all up, and my single cab needs about $1,000 so be properly "deadened".

You cover the gutted interior in dynamat or b-quiet or something, and then you lay down your foam, then your vinyl, then your carpet. You combine all 3 for the greatest effect. That starts adding up quick. But if you don't do at least the vibration damper stuff (like dynamat) you're not going to get very far. After having used that roofing stuff before (like peel and seal) personally I wouldn't waste my time with it again. Just my opinion.
