Do these mirrors mount at the factory attachment points?

Yes — these bolt directly to the existing mirror mounting locations on your truck. No drilling or bracket fabrication needed.

Will the mirrors stay stable when towing at highway speeds?

Factory-style mounting and rigid construction keep them locked in position under load. The powered fold function lets you retract them for extra stability if needed.

What wiring is required for the power and heat functions?

Wiring specifics vary by truck model — refer to your vehicle's electrical schematic or have a shop verify the harness compatibility before install.
