Yes. It is counterintuitive I know. But the issue is the resulting angles between the pin and the trailer wheels. By having the ball toward the rear of the pin-box, one is effectively shortening the wheelbase of the trailer. This results in the combination of the truck and trailer being able to navigate slightly sharper angles between the frame and the tailgate.
Now the other reason I like the Anderson ultimate is that the ball has 3 height adjustments. When I am traveling on good highways, I have the pin in the lowest position because for my particular setup, everything is nice a level.
But I have a steep driveway that flattens out at the top. So before I back up the drive, I drop the landing gear, raise the ball to the highest position to give myself an extra 2" of clearance for the tailgate. I would do the same if traveling on bad back country dirt roads.
