Dealer service manager and tech road with us on a trial ride. Said surging will most likely be corrected if I get a Moryde rubber pin box. But the clunking back and forth they said is normal for the hitch. But he did take a video of me stationary jerking it from forward to reverse and is sending it to Pullrite, so we'll see what happens next. Not sure I want to spend anther $1000 plus on a Moryde pin box just to stop some surging and bucking, but that will depend on how much the wife complains.
