I have the SuperGlide and it works for me. Never even think about if can I clear this or do I need to stop and slide it out.
I struggled with unhitching at first but realized it works every time if I do not take all the load off the hitch before I pull the handle.
Once I was at too much of an angle and had to pull the four pins to release the head from the base. Once seperated the head released from the pin box and I put it back together.
As far as it sliding while not towing I connect a bungee cord from the head to a tie down in the bed. That solved that.
I have no experience with the sidewinder.
