If it was, when it tried to rotate with the bumps it was probably moving somewhat laterally and not as much vertically, reducing the up and down travel of the chassis iteself. When it is level, or nearly so, to start with, it will move up and down and the trailer will have more vertical movement on the axle torsion unit absorbs the bumps better. In other words, the higher the angle of the arm, the less vertical travel it can have. If it could be moved to a 90 degree angle, there would be no vertical travel at all.
Dale, Well said. Andrews post on 'Start Angles' gives all of the information. The 'H' is the vertical dimension change. "L" the horizontal change.
Noob, As an example. You'd get about an 11"-12" no load ride height with a standard Dexter 22 1/2* up start angle using 14" tires. And 2.62" of vertical travel to full shock load. How low do you want to go? You could drop the frame in front and rear of the axle, say 6", and have a 5" ride height. Plus 6" of almost full storage under the floor. With the sides covering the frame, as Doug mentioned, you'd have a Low Rider Hot Rod.
