As stated above.Every camper is different. I'm at 26 to top of ball. 23 to bottom. I changed tires and gained a inch height on the trailer.
If your driveway is stright on the incline simply crank up or down until the distance between the frame on each end of the camper is the same. This distance will be real close to where you need to be on bottom of the ball.
Normal ball distance is 18 inch. I had to go to 26 to top for mine to be level.
