Pin box modifications

[Cardinalpuff]

I have a Pullrite 4100 superglide it sits low in the bed of my 2015 GMC 2500. I am pulling a 2006 30 foot Cardinal. The pin box bracket will collide with the top of the truck bed in a tight turn. I previously had a 33 foot cardinal that worked well. I think I need a shorter pin box. Is it possible to get pin boxes in different lengths?

Welcome to RVforums from Ely, Iowa. Sorry I am of no help on 5th wheels. Many here are very versed in them and will answer your questions.

Welcome. I’m guessing there is no adjustment on the hitch to raise it some. I think I would talk to the manufacturer I think Forest River and see if they can advise.
Definitely need some advice before making hitch adjustments. My opinion. Good luck.
