2021 380 FL Pin Box Hitting Retrax Bed Rails on 2020 Silverado 3500

[Brian_]

Hi all,

I was turning my 380FL around in a cul-de-sac and the Lippert bracket (maybe called the junction box?) of kingpin box made slight contact with the Retrax bed rails mounted on my 2020 Silverado 3500 HD DRW. I've since raised my BW companion hitch, but it is at the highest level now and it's still going to hit.

Has anybody dealt with this? Any insight on this would be MUCH appreciated.

Photo 1 - Black Lippert bracket that I don't know the exact name of. Hole circled blue is possible new mounting point that would raise the black bracket above the bed rails, but likely making the 5er sit off level. Green line is possible cut that would eliminate the problem. Red is collision point with bed rail.
Photo 2 - Rear view of the Lippert Bracket. Green line shows possible cut line and red circle is collision point.
Photo 3 - Angle of the truck/trailer where photo 2 was taken to show the collision point. This is on level ground, but it's a bit less when I'm unlevel.
