Does this mount to the factory bed rails, or do I need drilling?

It mounts at factory mounting points — no drilling needed. Just bolt it down to the existing bed rail system using hand tools.

Can I still access my bed while this is installed?

Yes. The roll-up design lets you open it fully or partially without removing the cover. Roll it forward toward the cab and secure it out of the way.

What kind of maintenance does a tonneau cover need?

Rinse it down with a garden hose and wipe dry after heavy rain or dust storms. No painting or special prep required — install it as-is.
