Has anyone measured the travel above and below horizontal in degrees?
An inquiring mind wants to know. And yes, I know how to measure it,
but when you’ve got the good reaction-arm brakes with sway bars,
it isn’t real easy. So I’m asking.

With the swing arm length 18 inches and the max up and down 4inches, I calculate approx 13 degrees up/down.

Here are my measurements.
The swing arm almost always has an upward angle, unless
you jack the coach up until the wheels lift off the ground.
At normal ride height, the swing arms have a 7 degree upward angle.
