The issue stems from the primer applied before gluing the optional light bar to the windshield (no fasteners are used in the attachment of the light bar). Is that typical in the industry, parts or components being glued onto an exterior surface instead of fastened?
Perhaps it's about minimizing the installation cost at the dealership.
The irony is that you'd imagine that an off-road roof mounted light would be something that you should be able to tighten when you are ... off-road.
I guess field serviceability isn't a design goal for these "off-road" trucks, but appearing "off-road" when going glamping is.
