Just replaced my tow vehicle with a new to me 2013 Duramax RWD 3500, I had a 2006 Dodge Ram with the 5.9 Cummins, Well, the dodge bedrail sat at 55 inches tall the Duramax sits at 57 inches so what do...
No that's with no trailer on it, stock hieght. My previous truck a Dodhe Ram 3500 RWD was at 55 inches, I think I can make some adjustments to either the hitch pin or the 5th wheel hitch itself.
