Reese Slider- Sliding While Towing!!!!

If the lock pin is in place you would have to shear the pin in order for the hitch to slide on its own. My Reese slider similar to others in this post usually needs most of the pin weight taken off of it before it will slide when I want it to slide. How often you slide is somewhat based on the design of the fifth wheel you buy. The first fifth wheel I had (Sabre) I would slide every time I backed up as the front cap was not cut back enough to clear my F-350 cab. My new fifth wheel is a Heartland Gateway and I have never slid the hitch, even when backing into a 90 degree spot as the front cap is cut back enough to clear the cab unless you try to turn >80 degrees or so.
