Well, the waiting is over. I went and brought my 5th wheel out of storage and found that the standard hitch will work. I had to move the hitch height up one notch so I don't endanger the box rails when on uneven ground. Camper/cab clearance is fine. The only issue I see is that on a sharp turn the camper pin box comes really close to the box rails. I could raise the hitch up one more notch but then the nose high condition will be worsened. As you can see in the picture it rides nose high, but it was even worse with my Dodge. No way around that.
