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

Its unfortunate that you are so against the Andersen Ultimate hitch, it could possibly solve much of your truck dilemma . It has the positions to eliminate the need for a slider.

I will let you know how much or how little I like the Andersen when I get rid of my dinosaur hitch ,and picture frame adapter . The Reese picture frame is heavier then the Andersen hitch
