Will this fit my crew cab Tundra with the extended bed?

This cover is designed for standard bed only. Crew cab models with longer beds require different fitment — verify your bed length before ordering.

Do I need to drill or weld anything to mount it?

Mounting method not specified in the product listing — test-fit before committing to fasteners or adhesive. Contact the warehouse for installation guidance specific to your truck's frame condition.

Can I paint this, or does it come primed?

Surface is black finish. If you want a different color, sand and prep per standard automotive paint procedures before application.
