Does this mirror use the factory mounting points?

Yes — this mirror mounts at the existing factory holes on your Ram. No drilling or frame modification required.

Will this mirror stay stable at highway speeds while towing?

Designed for towing duty on Ram trucks. The power adjustment allows you to set the angle once before pulling a trailer and lock it in position for the trip.

What wiring does the heater need?

Mirror assembly includes the heating element — you'll need to connect to your truck's 12V power source and ground. Wiring routing and breaker sizing depend on your specific Ram model and electrical setup, so consult your service manual for proper integration.
