That arrow points to the "leading" end of the torsion arm.

It also appears that the arm, as it goes rearward, is going slightly uphill.

Yes. The big crayon arrow is pointing to the back/aft/rear end of the trailing arm. You can see to the left of the big red crayon arrow the spindle and the brake backing plate with the brake wires going into the backing plate. You can also see the spare tire in its carrier. That would lead me to believe that this photo was taken from the back of the axle looking forward.

The tongue jack and safety chains are pretty good indicators as well.

So these arms are slightly below horizontal as the trailer sits, the spindle end is lower than the torsion end. That's what we like to see, right?

Except it is the camera angle from me crawling under the trailer. The arms are horizontal.

Okay, here are the promised Sport photos. This is a 2013 Sport 22. Thanks to Greg for letting us know about this, before it bit somebody:

It seems I recall a particular case in Florida where jacking up a 31'er caused the tire/hub/trailing arm/square shaft to drop...OFF? Now who could that be?

Great work Overlander63!!!

It worked its way out, then when the shock was removed, it slid the rest of the way out of the tube, and off the trailer. No massive hydraulic presses or liquid nitrogen involved.

These two pics from the factory are the best explanation I've seen showing how the "rubber meets the road" in a torsion axle. Not much of an angle seen on these particular fresh from the factory axles....

Flexiride makes the torsion arms adjustable with splines.
I could never understand why an axle manufacturer doesn't make the system with a steel tube insert inside a slightly larger axle tube. You could just remove a bolt (bolt would be used to keep cartridge assembly inside axle tube) and slide the old axle cartridge out and dispose of it and slide a new assembly in. If the axle was built with torsion arms like the Flexiride, then the only part to change would be the splined cartridge. There would be no more need to throw away perfectly good axles. The only part that usually goes bad is the rubber. As long as you don't spin a bearing, most of your axle components will last a long time.

Those photo's were taken by me, at the Henschen plant that was in Jackson Center.

Note that the shock brackets are still not attached at least at that part of the production.

Was that axle from that 1969 Overlander we replaced the axles on? The one where the axles disassembled themselves spontaneously?
