I have no experience with torsion axles. I understand what they are and how they work.
Any horror stories or strong reasons to avoid them on a GN horse trailer?
No.
Both of our 20' stock trailers have torsion axles, zero issues other than they do bounce a little when empty. One trailer has been to hell and back and is still going.
I've seen u-bolt breakage with spring suspensions and washouts, chitty trails, etc.. Actually IMHO that is why torsion is better, they don't break(knock on wood).
Obviously not an issue on actual roads.
