Does this toolbox come with mounting hardware and brackets?

Lock and key are included. Mount-specific fasteners and brackets are not confirmed — test-fit the toolbox on your bed and verify mounting points before committing to bolt placement.

Can I install this myself, or do I need a shop?

Installation is designed for DIY with basic hand tools. No specialized equipment needed. Have a friend help you position it across the bed to avoid twisting or binding during mount.

Will the aluminum scratch or show wear easily?

Aluminum will show minor scuffs over time with normal use — that's the trade-off for lightweight corrosion resistance. If appearance is critical, consider protective padding where the toolbox contacts the bed.
