I haved a 16K Pullrite superglide. It is an older model, but the fully automatic slide feature takes all the worry out of it. I am not sure we even need the slide with the 88 degree front cap, but with my short box, the recommendations I was hearing was pull rite slider. I found a used one, and the rest is history. I would buy another one in a heartbeat. At first, I used the capture plate that came with the hitch, and it screwed ( 9 screws) onto the kingpin area. I really prefer the quick on capture plate I have now held on by just one set screw. IF your rig ever had to be hauled by someone without a slider hitch, the capture plate must be able to be taken off. One set screw makes that easy.
