Do I need to drill holes or modify the bed to install this?

No drilling required. This cover uses factory mounting points on the bed rails, so installation is straightforward with basic tools and no permanent modifications to your truck.

Can I leave this on while driving at highway speeds?

Yes. The soft material is engineered to stay secure at highway speeds, but always check that panels are fully latched before driving. High winds or rough terrain may require additional inspection of the seal.

What's the difference between soft and hard tonneau covers?

Soft covers fold completely flat and are lighter, making them easier to remove when you need full bed access. Hard covers offer more rigidity and weatherproofing, but take up more space. Soft covers are better if you regularly need the bed uncovered.
