The ball height should never
be set to Airstream specs, but it can be used as a starting point.
Torsion axles are weight sensitive.
They also, in time, because of the aging rubber rods, lower the trailer.
The only "for sure" way to have a correct ball height measurement, is to measure it.
It will be different for each trailer as well as for the owner, due to the aging rubber rods in the axle/axles and pay loading.
Add about 1/4 inch to the ball height setting to the measurement.
