Will this mount at the factory rocker points without drilling?

Yes. This mirror uses factory mounting points — no holes to drill or modifications needed. Bolt directly to existing locations.

Is this mirror stable at highway speeds?

Manual towing mirrors are engineered for stability across normal highway driving. If you're towing frequently or at consistently high speeds, confirm your truck's service manual for any towing-specific mirror recommendations.

What hardware comes with the mirror?

The mirror assembly is included. Confirm your truck's factory fastener specification before installation — hardware may require sourcing separately depending on your setup.
