I’ve lived in this double wide for 1 year now. It’s a 1998. I’ve recently noticed these “dents” in the ceiling. There’s a couple on both sides of the marriage line. I’m not sure if they’ve been there the whole time or if they are just appearing. It’s not water related and they feel just as solid as the rest of the ceiling. Do I need to panic? Is it structural? Or should I just keep on living my happy little double wide life?
