Does this mount at factory attachment points or do I need to drill?

This tonneau mounts at factory points — no drilling into the bed. Install typically takes a couple of hours with a helper and basic hand tools.

Can I leave this installed year-round in wet climates?

Yes. The hard panel and sealing system are designed to shed water and handle prolonged outdoor exposure. Clean debris from the roll mechanism periodically to keep operation smooth.

What's the best way to secure it to the bed when it's rolled up?

The tonneau includes clamps and straps to hold it in the stowed position behind the cab. Refer to the installation guide for proper placement and tension to avoid shifting during driving.
