I'm Awesome
That's basically what I have, and you've heard my truck. But, there are some times were I think it's a wee bit loud in the cab. Windows-up isn't too bad really. Some sound deadener or maybe just undercoating under the bed to keep it from vibrating would probably help though.
If I could find the time to science I'd see if it's worth it. Ain't even got a roof of my shed yet.
I used noico 80 mil on my truck, seems to work well and was pretty easy to install.
