Well, my "NEW SAFER IDEA" has the problem of moving the ball back, and amplifying any up/down left/right movement of the car, Though this would be in town, extended, at lower speeds. My older, telescoping tubes under the trailer keeps the ball in the same place, near the bumper, but by drawing the tongue under the trailer on "suck up" moves the C/L of the trailer back, lightening the weight on the ball. They both change the weight felt on the receiver, but the "NEW SAFER" design adds unwanted sensitivity when extended.
Maybe I need a bit of both.
