It seems the newer receivers ('13 GMC and '12 F150) are made looser so they wont get rusted in. The problem is the hitch insert then clunks around a bit when in use.
I had that problem with a motorhome I had. The way I solved it was I went to Home Depot and got two of the lightest gauge galvanized angles they had, the kind intended to be hailed onto a 2x4. A little work and I could insert them as shims on two corners of the stinger. No rattle, and they are galvanized. They are cheap. Replace if they start to rust.
