Will this bolt directly to my truck without drilling?

Yes. This box uses factory mounting points; no holes to drill or modifications to your frame. Bolt down at the existing attachment locations and you're done.

Does it come with bolts and fasteners?

The box assembly is included. Fasteners are not specified — verify your truck's factory hardware before install, or source stainless bolts from your local hardware supplier to match the existing mounting holes.

How much weight can this hold?

Weight capacity is not listed. Test load gradually during your first use and avoid stacking heavy items directly on the lid to prevent flexing or failure over time.
