Get one like mine, It is a Delta Low profile box. I think it was just over $200 installed. I love mine because it does not block my view and I have a ton of stuff in there. The down side is you loose some bed space.
I don't like the box you have pictured, It is very shallow and it takes up alot of the back window, it's to tall imo.
Where did you get that box? Sounds like a decent price compaired to some others I've looked at.
I'm not a big fan of toolboxes, mostly because of their permanence. If you use you're truck like I do, you'll always wish you had that extra bedspace. I use a simple contico plastic footlocker ($20 or less). It fits under my tonneau cover, and I can pull it outta there anytime I want.
i like the tool box i have but i do wish i got the low profile one insted
but dont go for a cheap one you get what you pay for
my buddy fas one of them pepboys specials for like 90 bucks and you can bend it
mine was about 250,black powder coated, and you can stand on it with no problems
I have mine mounted through the bed with two lock pins. I pull the cotter pin out from underneath the bed and it comes rightout. Takes all but five minutes to remove my chest. It's pretty sturdy when it's pinned on the bed. Doesn't budge at all.
I sprayed the bolts and pins primer black, as well as the holes I have drilled. You wouldn't see the cotter pins underneath unless you knew that they were there.
