Unhinged. We have a 2023 Wonder BM and the headboards hinge out on an adjustable hinge. A few nights ago the headboard on my side fell on top of me! The hinge, secured by 8 screws fell off the wall of the RV! First, has this happened to anyone else? Second, how do you remount it? Do the hinges unlatch some way to open up? Thanks for your help!
