Mounting torsion axles upside-down (trailer?)

I've got a 20' trailer that I'm (re)building, that I received without any axles. From another off-road site I purchased a pair of towmaster "torflex" axles from a T-14 trailer.

Here's a couple pics and info of the trailer these axles were taken from (don't worry, the trailer was wrecked when I bought the axles)

My question regards mounting these axles. The axle shaft is mounted about 8" out from the center of the axle, so it rotates about the torsion spring. It's at (I estimate) a 20* angle from being dead even with the torsion spring housing.

My friend and I (my friend co-owns the trailer we're fixing up) were arguing about this, we both want the trailer as low to the ground as possible, both loaded and unloaded, but also realize we may very well bring these axles very close or even over their rated weight. I argued that the 20* angle should be facing up, and he argued that the 20* angle should be facing down. Either way we're going to be notching the trailer bed to tuck the wheels up farther, but I'm curious if it will be safe and alright to mount the axles in such a manner (and not risk having a wheel fall off or other bad things)

A pic to further illustrate this (I realize my description isn't the best):

my trailer has them mounted down so when the tire cycles in the arc it moves back and up in motion.

10k trailer with 225/75/15 load d tires on it.

should be mounted down, so when the suspension has load applied it can compress. the other way would be reverse loading the axles.
