5er hitch options RAM MegaCab w/6'4" bed - Solitude 310GK

Before you decide, check out the Blue Ox Super Ride hitch. It will mount with your gooseneck ball. It disassembles into pieces for easy removal/installation. It has rubber shock absorption for a smoother ride. It will articulate (not slide) rearwards for when you need clearance. It also has an interesting jaw design plus an embedded lube plate. Gets good reviews and checks all the boxes. Minimal amount of fanboys though.
