Can't answer about the different hitches (we have had Reese forever). But for those with short beds, DW's former boss had a short bed & did not get a slider. While backing the trailer into his driveway he wasn't straight and it went into his rear window.
We also added a rail saver to our Reese. One time the jaws did not lock correctly (although I saw the arm go back) and as DW was pulling out, you got it. Just a thought as well.
