I need to get this 89 cherokee about 100 miles from where it is now. Has anybody in here ever used a tow bar. I have driven tons of trailers and cars on tow dollys but never with all four of the vehicles wheels on the ground. Anything I should look out for when doing this (minus unhooking the driveshafts). This is the one I am looking at... http://www.harborfreight.com/cpi/ctaf/Displayitem.taf?itemnumber=94696 and I will be towing this with my 06 3.7l V6 but most of it is either straight or lightly downhill. Thanks for your input guys.
