Do these bolt to factory mounting points, or will I need to drill?

Factory rocker points—no drilling required. You'll use your truck's existing attachment locations.

Will these interfere with the rear doors on a crew cab?

These are engineered for crew cab geometry. Test-fit before final tightening to confirm clearance with your specific cab configuration.

Do I need to paint these before or after installation?

Painting is optional and depends on your finish preference. Install first, then mask and paint if desired—or run them bare steel for a utilitarian look.
