Do I need to drill holes to mount this, or does it use factory points?

This box mounts at factory mounting points — no drilling required. You'll need basic bolts and a wrench to secure it. Verify clearance with your specific suspension setup before final tightening.

Can I fit larger tools in here, or is it really just for small stuff?

Wheel well boxes are compact by design — think hand tools, fasteners, fluids, and small parts. If you're hauling full-size breaker bars or impact guns, you'll want a bed-mounted chest instead.

Does the lid seal tight, or will water and dust still get in?

The sealed construction keeps out weather and spray, but inspect the gasket before installing. If it arrives compressed or damaged, give it a day to recover or apply a thin bead of weatherseal around the lip.
