If using the SuperGlide, it interferes with your tailgate, wouldn't a Sidewinder or a manual slider do that too? The back of your pin box would be moved back while in a straight line. You could lower the tailgate. But then the tailgate would interfere with the front of the fiver.
You best option might be a long bed truck.
I cannot make sense of you SuperGlide problem. Just cannot understand how you get into a 45 degree turn on a highway. Or how the hitch want to pull the kingpin out the top. And why the pivot jaw spring would be so mis shapen in that one section. Appears maybe something foreign got lodged in the mechanism some how. Maybe something in the bed got caught in the wind turbulence? Piece of firewood? Stranger things have happened. How did those capture plate shims get dislodged? Was there a capture plate issue?
