Cardboard Headlining
Sux , plain & simple ~ if you ever use your truck in the rain , it'll warp as soon as the inside of the cab gets damp .
Trust me ,
everyone needs and wants , a headliner , often you don't realize it until you're finally sorted it out , then the differance is amazing .
I'd not consider a headliner of any typ un;ess it has sound deadening installed first .
I have a " soft " headliner , nort stock but very quiet in the cab so I like it a lot as this is my work truck and so needs to be nice for long drives , converstion and lisening to the News & Blues on the radio
There's been roughly a million posts on headliner installation , go search 'em all out , print and read 'em , get the water sprayer as that makes the cardboard *just* flexible enough to fit correcly , by the time it dries out , it's custom formed to your truck .
You can make your own out of Masonite , I bet Evan has done some sweet custom ones .
