I had much less problems unhooking with my SuperGlide after I learned to 1) raise the front end with the jacks until the separation between the capture plate and the hitch just begins to be visible then 2) place the truck in neutral to release any bind caused by the hitch pushing against the pin. It is not always done by putting in reverse. That would usually only be if your last move was forward when positioning in the site. If it was backing the trailer, forward might be called for, but usually neutral releases the bind either way. Sloping sites are a special problem. Be sure the wheels are well chocked on the downhill side so your trailer is not pulling/pushing the pin against hitch jaw. You might have to put the truck in gear for these cases. When everything is right, the lever should come out very smoothly.
