An improved trailer hitching system adaptable to quick coupling with both ball and pintel hook trailer couplers without the need to remove the pintel hook trailer coupler. The system incorporates an improved trailer hitch ball capable of meeting or exceeding all the Class I-V trailer hitch ball load requirements and dimensional tolerances yet with enhanced protection against crack development at the ball/ball stem. The ball can be sized for different purposes without being removed from the tow vehicle. It also includes a removable trailer hitch alignment system that can align both pintel hooks and the various sizes of trailer tongues. |
