New RAM short Box and B&W RVK3600 in rear most position

I think I found another 16K slider option. Demco/Hijacker has a slider that might allow me to use my existing double pivot saddle and head from my old Ultra 16K hitch (which I love) with their 6059 side rails, 5999, base rails, and 6059 picture frame. It only slide 8", and I have a few questions that I have submitted to them.

OH, and if I get close to or over 16K, there is an upgrade kit to make it a 21K rated hitch by adding a couple brace plates side to side.
