Do I need any tools or hardware to mount this?

Installation uses factory bed rail mounting points, so no drilling. You'll need basic hand tools for fastening. Hardware compatibility with your bed rails should be confirmed during install — some factory hardware may need replacement depending on condition.

Can I fold this open while driving, or does it need to stay fully closed?

The tri-fold design is built to collapse flat when you need full bed access. Use at highway speed only when fully closed and secure. Always verify your panels are locked down before driving.

What's the return process if this doesn't fit or work for my setup?

Contact ModSupply directly with photos of your bed and fitment issue. Returns are handled on a case-by-case basis; tonneau covers installed and used are typically non-returnable, but fitment problems may qualify for exchange.
