Do I need to drill into my bed rails to install this?

No. This cover mounts at factory attachment points using the included clamps — no drilling required. Installation takes basic hand tools and a few hours of your time.

Will this cover work with a tonneau cover spray-in bedliner?

Test-fit is your safest move here. Some spray-in liners create an uneven surface that can affect the seal and roll-up action. Measure your bed surface before ordering if you have a bedliner installed.

What's your return process if it doesn't fit right?

Contact support with photos of your bed and we'll work out the best solution. Our warehouse can process most returns within 30 days of purchase.
