Matching hitch up to trailer - Not exact - close enough?

Never mind about the ball height - I see now that I just have to turn the shank over to get the right height.

Getting the right ball angle is another question. The drawtite site seems to tell me to loosen the ball tilt adjustment, lower the trailer on to it and that where ever it ends up is the right angle. Is that the way to do it? I also read to play with it until the bars are level ??

Thanks
