5th wheel hitch recommendation

I have a Reese 15K Pro with a manual slider.
It's a basic hitch which has served me well. Nothing fancy.

LINK Trailersaver TS3 Air ride hitch. We have had excellent success with this hitch. Call Aaron and he will set you up. This is an expensive hitch, but worth every penny.

I recommend the Curt. Not sure how much your fifth wheel weighs, but I like my Curt. Bought mine on Amazon. I don't have a slider, but here is a link you can check.
