The bifold plastic shower door on my 73 sovereign
rear bath model will not close all the way. In fact, it is about 6" from being able to close into the track on the tub. I find that if I push VERY hard against the rear wall in the shower I can force it closed but then it bows in and looks as though it might break. My concern is that it is related to warpage/rear end sag. (I don't think the PO used it on the road much, if at all, and it was probably sitting in the same park for most of its life.) So far, I've not noticed any evidence of sagging from the outside. Has anyone encountered this problem? Any ideas what might have caused this? Thanks!
