My EQUALIZER 14K is very heavy. Probably over 100#.
I would never attempt to carry it with one hand. That much weight hanging off of one arm would throw my back out for sure.
I found a simpler cheaper more effective way than this tool.
First to remove the hitch:
I got a 5/8" round steel bar about a foot long. I insert this into one of the unused adjusting holes on the drawbar centering it.
Then I straddle the drawbar with my back to the tailgate. I grab each exposed end of the barstock and ease the hitch out of the reciever.
Then I walk slightly spread legged carrying the hitch with both hands and the weight perfectly centered beneath my spine. It probably looks a little goofy, but it really works.
Installing the hitch is a reverse of the procedure... I back in into the reciever. It really is pretty easy.
