Will this fit my bed without drilling or modification?

This tonneau mounts at factory points, so no drilling or bed modification is required. Check that your bed rails are in standard condition before installation.

Do I need to seal the cover before installing it?

The cover comes ready to install. If you want additional UV or weather protection on the panels, that's optional and can be done before or after mounting.

Can I roll this up while driving, or do I need to secure it in the open position?

Roll-up tonneau covers should be fully rolled or fully closed while driving. Secure it in your preferred position before hitting the road to avoid wind damage or noise.
