Recommend a tri-ball hitch receiver?

Hello,

I tow a few different trailers for teaching and at times for family. I currently swap between 3 different receivers with 3 different ball sizes. What would a good tri-ball mount with adjustable height be for occasional towing? In total, I may tow 6-12 times a year but must use my truck and these different trailers. Due to the infrequency, I do not want to spend a ton, but want something functional. Any help would be much appreciated.

Thank you

 

Thank you.

I found this in Google searching and was hoping for a less expensive alternative considering the few times I tow. However, if this is the "best" option, it may be the one I have to get.
