Does this box come with mounting hardware?

The box ships without bolts or fasteners. You'll mount it using your own hardware to match your truck bed or trailer frame — gives you flexibility to choose the right fasteners for your setup.

Will the aluminum rust if I leave it outside?

Aluminum naturally resists corrosion much better than steel, but it will develop patina over time if exposed to salt spray or harsh weather. A coat of clear protective spray extends its lifespan outdoors.

Can I mount this inside a pickup bed or on a trailer tongue?

Yes — it's universal, so you can bolt it to truck beds, trailer frames, or anywhere you have solid mounting points. Test-fit the position before drilling to make sure it clears your bed walls or cargo area.
