If you look at the trailing arm as the hand on a clock, starting at 10 o'clock and heading toward 12, as soon as you get to about 10:30 the movement is more forward than upward. Just seems all wrong to me.

Most everything has a purpose as well as being OK for a given use.
When we try to make sense as to "why" a torsion axle has such a crazy design, it all depends on the intended use.
The torsion arm angle can be most anything a buyer wants, within it's design limits.
Obviously an upward torsion arm would lower the trailer closer to the ground, but that also depends on the design of the frame and the size of the tires.
For an Airstream use, WHOA NELLY. Well maybe not, if we used 30 inch tires or so.
