An RV roof can be a very abusive environment with turbulence, flying debris, driving under limbs, heavy vibrations and more. I have not had any glass breakage that could not be accounted for, i.e, breaking for unknown reason. But, we have had hoodlums shooting at PV modules. Perhaps look at the back for a hole.<div><div apple-content-edited="true"><br>Larry<br><br><br><br><br><br><br>
