You don't state what your truck is, but does your it have the factory installed puck system for a fifth wheel hitch? BTW, that hitch looks like a piece of junk to me. Maybe usable, but a newer one would perform better.
And with that front end, you are more than likely to have contact with the cab if you don't have and use a slider - you state you have a short bed.
I'd look into a B&W Companion slider - heavy, but no chucking. Yes it is manual, but doesn't come with a lot of the issues with an auto slider - do your research. Or you can look into the Anderson hitch which places the trailer almost a foot back and is very light weight.
And people who say that they never used the slider function don't have a tight radius to make when backing. I don't use mine when backing into my storage space - but only because it a straight shot into it, and I only have to maneuver slightly. Good luck
