Rear steer axle. How does it work?

Lucy:

Carryfast:
A proper rear steer means that all the trailer axles counter steer to reduce cut in.

No, it doesn’t. It’s called a “rear steer” because it’s just the rear axle steering.
Trailers where all the axles turn are described as “positive steer”.

(Source for last bit - Rikki from here. He pulls 6-axle versions.)

I think you’ll find the man who has probably never driven one knows far more than this so called ‘Riki’ who pulls supposedly six axle versions. Be gone with you fairy tale woman
