Bed Toolbox/tote/storage

[Linz]

Hi Guys

I’m at the stage where I need to start thinking about getting some secure storage for the back of my pickup. I did a search and didn’t find to many recent threads specific to 67-72 trucks but if there are I apologize. I have a 72 longbed and would like to find a toolbox to sit flush or just below the bedside so I can put a tonneau cover over the top. I’ve been doing quite a lot of research online and there seems to be quite a few options. I want a decent one so a couple of questions are tool boxes tool boxes? As far as being secure and watertight etc in regards to the generic brands that you get at most ag stores etc. Aluminum or steel? And had anyone gone to the trouble of powder coating a box to match the color of their truck? Or is that an expensive road. An lastly how do most people mount these up the front of their box? Bolts through the deck I’m guessing?

Thanks
