What about Hensley, ProPride and the other hitch manufacturers that guarantee to eliminate sway. I realize when I bought my camper I received the basic hitch setup which is obsolete and I know the ones I mentioned are pricey but many people swear by them. Does sway happen with those setups also from time to time or are they really as good as the hype and worth the money they want for them? I would hate to go spend a bunch of money on one of those hitches only to learn that sway happens with them too. I just want to travel down the highway without being nervous all the time and reduce or eliminate white knuckle experiences.
