I used metal tapping screws and they have held up very well. You just want to make sure they are just long enough to thread but not stick out far. They are placed to that the screws stick out inside the void of the bed side and are not visible. The ones I have that are at the top of my bed can only been seen if you look down between the bed and cab from above. this is very important to not have them be too long as they would hit the cab and scratch paint off allowing rust to form when every the truck flexes in any way. There is plenty of room there so noting to be too worried about unless you using over a 2" screw.
Any noticable rattling from the toolbox while driving? Not so much concerned with the cover, but Id imagine the box might make some noise???
There is no noice from the box. Maybe if you had loose hand tools but it would be quieter than a normal truck bed tool box.
This should be sold as a combo package.
How did you attach the x trac you had in your truck bed

Badass. I need this.
Highly recommend. I have had it on my truck for about a year now and the tool box has held up very well with all the tools I throw in it.
