04/27/2023, UNKNOWN OR OTHER,EQUIPMENT: The solar panel mounted by Thor on top of the van detached and flew off while I was driving on the highway and encountered cross wind. From what was left on the solar panel bracket, it looks like there were cracks in the metal around where the bolts were attached for a long time.
