Sitting here waiting on my Pullrite hitch to arrive. I measured the top of the bed rail from the ground,looks like 54",any problems with that Heath & 5th wheel hook up?I kinda did a search,as I think that this is prob ally a old subject. Is it effected by just certain 5'ers?I have a 2003 3500 slt,2wd,srw,ls,ho,6spd,lb,qc. ,sorry if this is old stuff. I'm sitting here thinking up future problems,idle hands ,etc. Pat
