Will this bolt straight onto my truck without modification?

Yes. This cover mounts at the factory attachment points — no drilling, cutting, or custom brackets. Bolt it on with basic hand tools.

Does this come with all the hardware I need to install it?

The cover itself is included. Verify your existing fasteners are in good condition before installation; you may need to source new bolts if yours are corroded or stripped.

Can I paint this, or does the black finish need any prep?

The black finish is ready to use as-is. If you want to paint it a different color, wash and scuff the surface lightly before priming — standard automotive prep applies.
