I'm not a Ford engineer, and I don't play one on tv, but when I replaced my OEM hitch receiver with a DrawTite unit, the difference was night and day. Better design, perfect fit, very strong. The factory hitch used to wind up when I snapped up the bars, over 1/8", but the DrawTite doesn't measureably move. You'd need a dial indicator to see any movement. I would trust Reese, and I presume the rest are tested and safe also.
