Rear Hitch Receiver

I am in the middle of the same project. I watched OfferUp and LetGo apps in my area for 2 or 3 months for a truck bed toolbox, the style that rests on the bed rail tops at the front of the bed. I got a Kobalt brand, aluminum diamond plate, spacious, has latches and key lock, in very good shape for $35. I'm bolting it to a hitch carrier which will go in my Curt Class III receiver hitch bolted to the frame of my travel trailer.

I'm getting ready to go full time. Adding a hitch carrier to the rear hitch receiver on my trailer will give me some nice storage for those less used items.
My idea....get a hitch carrier, the size is 60Wx20Dx6H, then I want to add a box that will fit in the carrier that I can lock. I like the diamond plate boxes but can't find a decent size for a decent price.

Have any of you done this? Ideas on boxes? Pictures??

Thanks!!
