Simple but ... need toolbox recommendations

Currently have a roll n lock but want to ditch it for a cross bed toolbox . Looking for your recommendations on both the box , and the mounting hardware .
What box fits best, and is the slickest setup
if I can have my preferences I’d go black box , and maybe with a small cargo rail on top .
Thanks !

 

I have the Kobalt from Lowe’s.
I’ve had it 13 years now. So far it’s been great.
I used the J-Hook method to install it.
But there are better ways to install it.

I have the Toyota branded box on mine, a bit pricy for what it is but it integrates nicely with the bed rail system. I think they are made by DeeZee but I'm not sure if DeeZee sells a Tacoma specific box themselves.
