Newer 5ers, Slider Hitch Required For Short Beds?

Been RVing with fifth wheels and short beds without sliders for 25 years with nary a problem.

And BTW, the rounded corners on fifth wheels is not a late developing concept, has been here a while.

I have never heard of 90 degree jacking a 5er and continuing on with the jack. That only takes place on the keyboard or down at spot whatever where the stories al start with one upon a time. :B

And if my day is coming it better hurry since I am pushing 80.
