Will this mirror mount at my factory attachment points?

Yes — designed for OEM mounting points on your truck. No drilling or custom brackets required for installation.

Does the heater element work independently from the power adjustment?

Heating and power adjustment are separate functions. You can run the defrost without adjusting the mirror angle, and vice versa. Refer to your vehicle's manual for wiring integration with your existing controls.

What about stability at highway speeds?

Power mirrors are engineered to match OEM vibration and wind-load specs for your truck. Mount securely at factory points and the mirror will track true at any speed.
