Sound deadening and rhino line

[conoco]

Looking for suggestions or recommendations. I am currently replacing my rockers and have stripped down the inside of my cab. I am hitting it with a wire brush and then will prep everything for paint. I would like to instal sound deadner on the floors, doors and all the way up to the bottom of the rear window behind my gas tank.
I dont know what order to do this in. I dont want to install carpet and there would be to much moisture with all the snow here in alaska. I would like to just have the bottom rhino lined. Do I spray the rhino liner on top of the sound deadner. Anyone have suggestions? Thank u.
