Does the height compensate for the ball coupler you have to install on the kingpin?

It occurred to me after posting this that the Andersen system is not adjustable for height, unlike typical fifth-wheel hitches which have multiple holes in their brackets so that they can be assembled within some range of heights. That makes knowing the actual height of the Andersen "Ultimate" hardware more important.
The total of:
- height from ground to floor of truck bed, plus
- total height of Andersen rails, frame, ball, and coupler
must be within the range of height that the trailer's pinbox plate can be above the ground.
Since I'm curious about this, I just sent an e-mail message to Andersen asking for this height.
