reversing that would be interesting
If it was attached rigidly it might not be too bad to reverse.
Infact ur problem would be getting it to turn with the 2 axles so far apart it would want to stay straight.
If just hitched on would be a nightmare.
Those trailers are bad enough s they are so narrow and short by time u see it in the mirror its already jack knifed.
When i worked out bush on farms in Oz had a trailer with a front dolly on it, i could never get my head round reversing it.
As u reverse normal steer 1st, then oppisate then reverse again.
Just if i got my head round that would get sent on the articucated tractor, u reverse it like a normal trailer but looked funny with the artuculated back end.
The grader driver out bush used to have his grader hitched to vibrating roller, hitched to fuel bowser which towed his pick up and carvan. He just drove between jobs, albeit at about 10mph.
Totally self sufficent.
Welly boot still see tractors dragging 2 silage trailers or a low loader trailer with digger/muck bucket on and dump trailer or muck spreader behind.
No idea the actual legality thou but see it often enough
