So, I just got a 5er this spring and have the Pull-Rite 16K (non-slider, just super 5th) and Revolution (activated since I have a short bed). And I have never had an real issue. Much like with a bumper pull, you may have to relieve pressure on the hitch point by backing up or pulling forward slightly, depending upon slope of ground and where the pin is resting on the jaws. But if I do that and lift the trailer so that I start to see a bit of gap at the front of the king pin plate, I never have an issue. I love the combination and love that the pull rite snaps into place automatically telling me that I'm hitched tight. Took a few times to learn the right height for camper to hitch but now its a piece of cake! And my dealer even recommended the Pull-Rite hitch for me.
