Hello,
Lots of opinions you will find on hitches here...
We have a vintage Bambi and the "original" type hitch, but we have a anti-sway device we purchased that goes on the side... even though our trailer is small... hubby said this made a HUGE difference in towing.
Here is a link to a long, but very informative thread by 2air...

Good luck! Hope others respond to your question as well. Remember, this is just one little old lady's opinion!
