  2. Filed Dec 21, 2024Failure Dec 12, 2024Lakehills, TXUnknown or other

    Driving on I-10 on December 12, 2024, the Solar Panel flew off the roof of my 2021 Thor Chateaux 27R and into the ditch. My wife following the RV in our other vehicle saw it happen. Luckily no one was hit by the panel as it could have been deadly serious. Looking at the roof later, I found two brackets (of a total of 4) still intact but missing bolts while the two brackets on the other side were gone with only two small screw holes in the roof. Months before I found one of the brackets loose at the solar panel and secured it. All the other brackets were tight.
