Do I need to drill holes or modify my truck bed?

No. This tonneau mounts at factory rocker and rail points — no drilling required. Clamps secure to existing anchor locations.

Can I paint or seal this before installing?

Mounting clamps are pre-installed and ready to go. If you want to refinish the cover itself, remove it from the clamps first and handle prep and paint separately before reattaching.

What's the return window if it doesn't fit right?

Test-fit the clamps at your factory anchor points before securing them permanently. If mounting geometry doesn't align with your specific truck, contact support with photos of the clamp placement for guidance on adjustment or return eligibility.
