Headliner sagging in 2007 Suncruiser we are looking for any ideas to make this right. No I'm not going to thumb tacks. Called Forest City and they can do it for $1500.00 per each 4' section x 9. Don't believe we will go that route. We are looking at carpet & auto headliner material. Thanks for any help did not get any from Forest City and did not seem to care.
