I've had the Centerline WDH since 2011 and love it. I experience ZERO sway with this system. Also most of the parts have a lifetime replacement warranty, but I haven't had to replace anything on it.
Yes the hitch is heavy, and yes you do have to be in a straight line to hook up and un-hook. Only once in the 4 years of camping did I have to unhook before I backed into a really tight spot. But given the length of your trailer, I doubt you get into small spots LOL.
Sure you can spend a lot more on a system that is maybe superior, but at the price range of the Centerline and the performance it's provided me, I wouldn't bother spending more money on another system..
