Gettin the rig ready for first trip. The mirror that is in the cabinet door when you enter the front door of the trailer has been coming out for a couple years now, and I am in the process of re-installing it. It has been secured in place by what appears to be a bead of glue from a glue gun. Has anyone else had this problem and repaired it themselves? I am not sure if I want to repair it the same way, as it may just come loose again. Any suggestions?
