Mark, the one Kiphorn shows could be what you need. 3 balls and a pintle. Just imagine going down the road and coming across a young lady in distress because her horse trailer needed moving but her Suburban just blew a hose. Shes worried about the horses needing to get back in their stables before night fall. All she has is a pintle setup on her quadruple horse trailer and no one can help her because all they have is a ball setup and only one 2" ball at that. The lady begs you to help and indicates her hookup is different then most and you tell her on your way to look at her setup that it's OK, I got 3 balls and a pintle to boot. Shes impressed and was not aware that there were so many types. You kindly explain that its very simple, I simply back up, take your hole and put it on my pintle and wham bam its done. Same could apply to some of the guys at the construction site who prefer pintles. Rat...
