How many square feet to sound deaden the entire truck?

Did a quick search on google and here, and didn't come up with anything. As the title states, approx how many square feet to put a single layer in the entire truck? I've got an access cab, but anyone that knows the square footage for other cab types and posts it here for other's use, that would be fantastic.

 

you should call rick at raammat. He is great and can help you out with that. Im not sure exactly how much you need

 

Check some of the other posts because other people have done it. I think it also really depends on what you want to do exactly.
