The GM tonneau cover uses a velcro strip with adhesive on the back to secure the cover to the drivers side door jamb. I have not been able to get the velcro to stick for very long. Has anyone come up with an improved solution? Is there room between the jamb and the door to us a snap fastener? Maybe pop-rivet the velcro to the jamb? I am open to all ideas, and very willing to drill a hole or two to make it work.
