The pin/arm itself is normally fixed relative to the trailer, AND you can normally adjust the height of most (non-slider) hitches, but IIRC the SuperGlide aut-slider hitches may not be height adjustable.
I use a Reese Titan 16K hitch (with an unlocked revolution pin arm on our Rockwood), and you can adjust the height of the Reese hitch (5" height range, with 4 stops)
Why do you need both the Revolution pin-arm, and the auto-slider hitch ?
Reese say not to use the Revolution in a slider hitch (I went through a lengthy process of discussing with them myself, and spent months investigating options when getting my 5er, originally with an F-150 short-bed).
You definitely can't use an auto-slider like the Pullrite with the Revolution arm unlocked, since you'd have two pivot points and the Pullrite relies on the rotation of the pin in order to work, AND you'd end up dangerously unstable.
You could leave the Revolution locked, and use it with the slider, so that you get the length of the revolution arm, in conjunction with the slider, even tho' not recommended by Reese, but you wouldn't get any benefit for turning from the Slider, compared to just using a regular hitch and unlocking the Revolution, since the rotation offset of the Revolution (22") is more or less the same as the Superglide (22 3/4").
Unless you have a super-short (5.5ft) bed I'd suggest using a regular hitch and unlocking the revolution hitch. I have a 6ft9in bed and with the Revolution pin arm unlocked I have plenty of clearance in a regular hitch (would be 9+ inches with the truck at 90 deg to trailer ... if I could actually turn it that sharply)
If you do have a < 6ft bed, then I'd still probably suggest using a regular hitch and unlocking the Revolution, since you should still have quite a lot of clearance for most turns (no less than just leaving the Revolution locked and using the SuperGlide) and just need to be wary on unusually sharp turns.
The only option I considered to give more clearance on a 5.5ft bed was to unlock the Revolution and use it with a manual slider (not possible with an auto-slider), for when making exceptionally tight turns), but I eliminated this as being more hassle than it was worth, especially given how rare those situations are.
Let me know if you have any specific questions, I've been through most of this myself, and know how confusing some of it can be. Good luck !
