Do I need fasteners or adhesive to install this?

Mounting method not specified in product data — test-fit the box at factory points before deciding between bolts, brackets, or adhesive. Check your truck's wheel well for obstruction first.

Will this box survive weather and road salt?

Hard panel construction holds up to moisture and salt spray, but wash it regularly to extend the lock mechanism's life, especially in coastal or winter climates.

Can I access the lock if the truck bed is full?

The box mounts inside the wheel well, so bed cargo won't block you. Just make sure tire clearance isn't an issue if you run oversized wheels—measure before ordering.
