The only thing that I would add to this thread is to choose a steel tow bar over the Al tow bar it will have a higher tow capacity. The Al will be lighter but I only remove mine once a year for the winter. Also when you install the tow plate make sure the bolts are grade 8 bolts and use the Loctite(blue stuff)or Thredlock to keep the nuts from backing off. I know personally two people who have lost their tow cars one was a Blue Ox Al bar that failed, another where the base plate came off. Occasionally you read on here of the same kind of failure. Some people install a safety chain around the the base plates for added insurance. I check mine every season. My tow care weights 2500 lbs and my steel Demco tow bar is rated for 10,000 lbs. I have dissembled and cleaned it twice in 12 years and 80,000 miles of towing to keep it locking.
