I did the 2 part sound deadening in the doors of my duramax and it made a huuuge difference. So I’m definitely planning on doing that with the 74. When i insulated the cab, many years ago, with fat mat, i also did the doors, but after years of monkeying inside them, I’ve had to remove some of it. Can’t wait to gut the interior and meticulously go through and insulate everything in hopes that it’ll be a nicer experience for low stereo volume situations haha Having the ability to tear the truck down and not have to hastily get it back together for work/school in the a.m. has made working on the truck muuuuch less stressful
