I've never had a torsion axle trailer but this is my second leaf spring trailer. On both trailers the front axle bent and subsequently had to be replaced and both trailers had the equalizers (both triple axle trailers). The trailer sat level all year, it was level when it was hooked up to the truck too.

All my friends who have torsion axles never have any problems from what I can see.

Again, I've never had one so I can only speak from my own experience. How about everyone else?
