This is what I put on my truck, ordered it from Alibaba. Took a month to get it shipped from China but I am happy with it. I have seen the same one on Amazon at double what I paid. Had to buy a cheap Harbor Freight metal cutting saw to cut down the tube parts to get it to fit, pretty easy to do...
I went with these Husky bins that fit great side by side and then put a harbor freight bed bar to hold them in place. Pretty cheap setup and work great. Can’t take credit for it as I saw it on another post.
