I am going to be towing my 66 chevelle to and from the track eventually. What Hitch do I need. I have a 2012 Ram quad cab hemi. Owner at Hitch store said I would be fine with a hitch rated at 6000lbs and 600 lbs tounge weight. Does this seem right? Car weighs 3400lbs. I am guessing the trailer will be about 2000lbs.
