Will this box sit flush in my truck bed, or will it stick up above the rails?

The 10-inch height keeps this box low-profile; it won't block visibility or catch wind. Check your bed dimensions against the 50x13 footprint before ordering to confirm it fits your layout.

What do I need to mount this to my truck?

Mounting hardware is not included — you'll need to source brackets or fasteners suited to your truck bed design. Test-fit the box first, then decide between bolt-down, clamp, or tie-down straps based on your setup.

Can I leave this outside year-round without maintenance?

Aluminum resists rust, but the lock and hinges can oxidize over time if exposed to constant moisture. A light coat of protectant on hardware once or twice a year keeps everything moving smoothly.
