shedender:
After coming to a stop and there is no damage how do you get out, can you drive out of it or do you have to unhitch the trailer?
Depends on the circumstances shed. In no damage scenarios, are they true jacknifes, I guess you could drive away but you’ld have to do a pretty thorough check before going to far.
In my case the wrecker pulled the unit back onto the road, unhooked the trailer for a second unit to tow back to the depot and the damaged unit went back with a front lift.
In other circumstances you might have to tow the trailer back to staighten out or even crane lfted back onto the wheels.
