Very handy. I could sure use one of those. Might just have to put it on my wish list.This is a Rapid Hitch. It is solid aluminum and adjusts for different height trailers and you can change ball sizes by turning the holder upside down. I have two different trailers with different ball sizes and different heights. I need only one hitch. Not cheap, but effective and they have different sizes plus a locking pin set that is nice.

I turn it upside down for the RTV. The smaller one would be better, but this works.
