Storage container under rear seat ext-cab

[1buda]

Looking for some sort of storage box/container to fit under the rear seat of my ext-cab to store stuff into. I've found a few but the price is way out there.

I used 1/2" MDF and speaker box carpet to build mine (98 x-cab). Use card board to make a template first.

I was thinking about buying something cheap, I'm to lazy to build anything right now.
