Installing tie-down cleats in bed

I am an exploration geologist with an '06 taco. I need to outfit the truckbed to accomodate shovels, tools and other weapons of the trade. Does anyone know of the best way to install tie-down cleats or hooks in the plastic? Any good way?? Thanks.

 

might not be what you are after but these are the only "tie-down" options I've added.

If you drill in the bed to mount thing's, use large area backing plates on both sides.

What about a box or container that is strapped down for the smaller stuff.

Also there is the bed rail system, which is a bit high in the bed to mount a lot of stuff to, but is a goo point to anchor off.

 

I have a Rubbermaid box (bought at Walmart) that I can store stuff in. I did glue in wood ribs that match the reinforcement ribs so the box would not slide sideways.

What I need is small, not large load-bearing mounting tie-downs. I believe the plastic will bear the load and stress associated with mounting shovels and lighter tools. I plan to drill through the plastic and just mount screwed-in hooks. I was hoping for advice about what the plastic will bear and what I can get away with in drilling or screwing fasteners in.

 

No screwing.
Drill and use a nut and bolt with proper washer's and backing plates to spread the load. size of fasteners depends on what is being supported. For a shovel I would think 1/4 or no more than 5/16 is all that is needed.

Use spacers similar to the ribs you put under your storage box so you are solid when bolting down, no void, must be solid, this is key to long term stability.
