@Lynnmor: I understood you before you got to "Camber changes with load as the arced axle tube straightens." Can you break that down a bit?
Sure. The axle tubes are bent upward a bit causing the wheels to be tilted out at the top. As the load increases, the axle will straighten and the wheels will move inward. The tilting is called camber. When I say load, that includes the bare trailer and anything added. As you can see, the wheels will be perfectly vertical only at one specific weight.
If an axle were to be flipped, the bend would already be down with the wheels tilted in. Any increase in load will make the tilt worse.
A small amount of off camber isn't critical or there wouldn't be many trailers on the road. As I described above, the camber is only perfect when the load is perfect. An axle that is actually flipped would progressively get worse as the load increases.
