Ouch! Can the pin box be lowered and the suspension raised? That would get more clearance. That said I pull with a short F350 with the factory mounts (pucks) and do not have a slider. My insurance co paid $500 for me to learn I needed the slider. That said, I still have the same setup but am careful when backing or making U-turns (when my "oops" happened) and the factory mounts are super convenient. Sine the initial "learning" event we haven't had any serious issues turning.
Most dealers will tell you anything to close a deal, I rely on them to provide a cost that we can debate, I do my own research for everything else.
