Not sure how the new Grand tows, have two buddies that tow with older grands, ZJ and WJ. Can't fly up the hills, but they get the job done. I tow with an 04 dodge 1500 hemi. Does just fine for me. I can cruise at 65mph and have plenty of power to pass most cars and other trucks going up hills. If I had to do it all over again i would look for a 3-5 year old diesel and once I found one in decent shape that would be my tow rig.
