Hiya, Northern Ireland Trailers operating out of Preston Dock ran five axle
outfits back in the 1960s in the form of two axle units and tri-axle trailers,
I recall dragging one to Norwich with a bog standard TK it took me forever
I was working for Killingbeck at the time, these trailers had a floating back
axle which you had to lock up to reverse into your drop and release to run
normally, I rather think I was way over the pop when loaded outgoing, but
rarely got into top gear when returning to Preston empty.
