I am bringing it to the dealer. I am thinking the issue is the slide function is making the trailer move back just far enough that the pin mounting bracket is hitting the tailgate. i will take photos when i hitch it up again to move it. No i did not lower tailgate to move it. My truck is not jacked up its original equipment and 4x4. i can say that the way it is hooked up right now it will take out the sides of my bed in slide mode when it comes around. that is definite. The part that will hit is the bracket and yes it may be needed to cut off part of that bracket. I will transport to the hitch dealer but the the mechanic told me they have never installed one of the hitches yet they sold it to me... HMM>
