Without the seat there is a ton of room back there...lots of ideas about what to do with that space. It allows the driver seat to be laid flat. That one is electric. Funny though, the passenger seat which is mechanical wouldn't go all the way to the floor. Oh well.
I'll let you know what I find out about the noise issue. Maybe just some better fitting sound-absorbing insulation would work better than the 'felt' used now.

Jeff, it's the vents. I dynomatted the back wall and put 1/2 inch noise insulating aerospace foam in there from one door to the other and on the floor/storage area.
It was quite a bit of work. Then my girlfriend went for a test drive with me and she said, "you know, I think that all the noise is coming through those vents". Gees, and I just did all that work.
She's right. What I did was like putting in super insulated sound deadening windows in your house next to freeway and then cracking the windows open!!!
Yes, it is quieter with the sound deadening - definitely. But a way to really quiet those vents is to baffle them. I haven't gotten around to it, but I'm sure that you could cut at LEAST 3 db of noise out if you could block the noise coming through that vent. That means you would need half the radio power that you would need now and it would still sound the same.
That's a lot. Usually that's the max you can get on a whole vehicle when you dampen *everywhere*. With the Tundra, you're starting from a pretty quiet beginning. They even have (small) pieces of dynomat on the floor coming from the factory.
Fortunately you have the seat there to kill the sound or it would be intolerable.
