Will this mount at my truck's factory anchor points?

Yes. This cover mounts at factory rocker and bed rail points — no drilling or custom brackets needed. Install is straightforward with hand tools.

Do I need to prep or paint the panels before installation?

The panels arrive ready to install. No priming or painting is necessary out of the box.

Can I open this partially to access just part of my bed?

Yes. The roll-up design lets you stop at any point — crack it open for short loads or roll it all the way to the cab for full access.
