WDH - wife friendly

Then I am going to speculate that you're doing something wrong. When done properly all it takes is the pinky finger of your left hand to rotate the bar into place. No tools required.

Any wdh will have the load off the tensioning system when you raise the connected hitch enough. That is after all the purpose of the wdh, to raise the hitch by creating tension somewhere. OTOH there is no way to connect a trailer and tow vehicle without operating the Jack.

So +1 to EchoGale, get an electric jack and see if your wife can become comfortable using it. If she can then probably any wdh will work for her.

The fastway E2 goes on with absolutely no force at all. The biggest problem with these systems is knowing how to use them. The E2 is installed as follows. Once you have lowered the tongue onto the ball, and locked it in, you should now begin jacking it back up. You will actually start lifting the tow vehicle (the body will raise up, not the tires). This will first of all, tell you that you are absolutely locked onto the hitch. And secondly, it will make it so the spring bars simply just drop onto the cleats on the tongue. That easy, no lie. You will have room to lift the bar a 1/4 of an inch above the cleat and let it drop onto it. I use the square spring bars, not sure if the round bars work this way. I have never ever had to force a spring bar on, or off. Good luck with whatever decision you make. 

I use the Anderson for exactly these reasons. I had one rule when I bought the camper. There would be nothing that I could not do by myself. The Anderson was more expensive than other choices but it was chosen under that rule.
