Those kind of WDH rigs are designed to fall out of their sockets at near close to 90 degrees (or perpendicular) to the rear of the vehicle so as not to damage the hitch or the trailer, or both. If you are anticipating extremely tight turns, you might consider removing the bars first (ie: backing into a tight spot). If you are moving forward, the only time this will happen is when making a full u-turn. That is something that you should never do with a trailer attached anyway.
You can change WDH rig, but you may damage your hitch or your truck by making continually tight turns with the WDH attached no matter what rig you use. Make sure the connector heads are greased well, and that the ball bearing retainers are working properly.
