I wonder how hard it would be to glass the back of them for added strength.
The only place mine cracked was around the screw holes, and the recesses for the screw holes. I think someone creative could reinforce just around those areas. Glassing the whole back sides IMO would just increase the weight and not help.
I found that my driver side was in much worse shape than the other side. I had assumed that was because that side gets all the sun in our parking location. But today I realized that the struts they used to stabilize the lower sheet metal were worthless, and what little there was had vibrated loose. This is along the slide-out. So today I welded in some real struts to stabilize along that side and I'm expecting to see a lot less flexing in my rearview mirror. The passenger side is not a slide-out, and the sheet metal was well supported, so the plastic fender skirt is well support too.
