You're probably going to get 50 replies to this, so let me
have the honor of being the first ;-)

It's a fluid dynamics thing.  Vents facing backwards is *correct*.
The flow of air over the vent creates like a vacuum behind the
vent that sucks the air into the trailer.  So, you get an even
flow of fresh air into the trailer without the ramscoop-like effect
you'd get if the vent faced forward.

Any trailer you see, human or horse, is going to have vents
facing backwards.
