Headliners are easy, yes they do come apart on cars, RV's, trucks anything with a headliner has gravity and gravity wants to pull down!!! You can replace the headliner with anything you want. I have done vinyl, fabric, headliner material, canvas etc... I have done tons of them. Never on a motor home but it really is the same job no matter what. easy steps too
1. Remove trim to take the headliner down
2. use caution here but remove and peal back the old headliner.
3. If you removed the foam or backer as well its now time to sand and scrape it all off to get down to a smooth surface.
4. Clean the surface even better! yes and get it as spotless and smooth as you can.
5. Cut an outline of the material that you will need giving yourself a few extra inches to work with.
6. Use 3m(important as it is the only one i have found to hold over years) Spray adhesive. The RED can not the Green one... Once again THE RED CAN! I know its a touch pricey but you need it to stand up to the heat.
7. Spray both the headliner backer and the material that you are going to use then let it sit for a while and tack up, you do not want it to be wet when you apply it...
8. Starting in the center lay it down with as few wrinkles as possible. When you get a wrinkle stretch it out, use muscle but don't rip...
9. Trim excess material and pin back any if you feel the need to keep excess.
10. Cut any holes from the top in an X pattern stopping before the point that you need to. Then round the corners in hopes not to create a running seam to rip on.
11. Put the headliner back in place(sometimes easier said than done but with two people in an RV you should be fine
12. Re-attach trim and accessories....
13. Enjoy and brag, you just saved hundreds vs having a shop do it...
to repair old headliner
1. inspect and clean all surfaces
2. remove trim and sagging panel
3. inspect and stretch to see if it can be put back into position (This will requite some muscle and finesse
4. clean surfaces
5. apply spray adhesive then let tack up
6. stretch and place old material back into position and hold it there for while while it bonds.
7. re assemble
It's as easy as replacing or fixing a headliner!
