Do I need any extra fasteners or hardware to install this?

No additional fasteners required—the clamp-mount system attaches directly to your factory bed rails. You'll need basic hand tools like a wrench or socket to tighten the clamps.

Can I open this cover while the truck is moving or parked on a hill?

Roll-up tonneau covers are designed for stationary access. Always park on level ground and engage the parking brake before rolling up or down the cover to prevent accidental movement or damage.

What's the return window if this doesn't fit my truck?
