One size don't fit all here as each short bed truck/5th wheel trailer combo is different unless they both are the same.
GM has had a longer dimension from the back of the cab to the trucks rear axle and some GM owners have found a sliding hitch wasn't necessary with their particular trailer.
My short bed Dodge requires a sliding hitch with my current trailer. Its not needed making corners on city streets but mostly in tight maneuvering conditions while backing around a corner in a camp ground.
As AUWing says I also like to slide the hitch in the aft position while backing, the trailer reacts quicker with less steering input.
I also have no problem with the trailer being farther behind the truck when the slider is aft. I never tow on the road with the hitch in the aft position.
Non of my trailers have had any issue with sliding the tires sideways while making a 2 point turn or pin box/hitch issues in a 90 degree situation.
Your topic is very long and may ask why do short bed truck owners buy a sliding hitch when its not needed. Good question.
IMO... some fall victim to so many folks telling them they have to have one even though the hitch maker and/or the trailer mfg/dealer say differently.
