I have a 2002 4x4 6speed and want to put in 5th wheel. Having problems with truck being too tall for kingpin height. Truck is stock suspension. 6 speed 2500 4x4 has bedrail height of 58 inches. I am looking at trailer that can have pin height around 47 inches,maybe 48. Not sure how to get height lower without major work. Flat bed and low pro hitch? I'm at a loss on what to make this happen. Maybe someone on here has ran Into this before.
