My install was Jan. 9 and I got my headliner kit a few days ago . I opened the QR code link and it just took me to the Headliner upgrade kit page on the GFC website, no instructions. I’ve done online searches and can’t find any headliner install manual or instruction from GFC. There is a thread on this forum from a guy who posted a photo using white tape - see " Installed the GFC headliner in my V2 Pro" The white velcro tape is hard to make out against the white camper roof but you can kind of see it. Cheers.
