Tool box under mx4 tonnue cover

Anybody know of any affordable tool boxes that will fit under a mx4 tonnue cover? For a DCSB 3rd gen Tacoma

 

There are about a million options out there depending on your needs. How secure do you need it to be? How big?

I've been using this box for about 15 years and it's worked well:

Same company makes bigger boxes too:

If you need something more secure, get metal. You'll be into it for a little more cash.

 

Those look durable. and great that there made in the states. I was thinking something metal that bolts to the bed and stays tucked under the bed so I would be able to close my tonnue cover
