I had to back up once, with a truck camper towing a Jeep. In about 4 feet (maybe 5), the front wheels of the Jeep SLAMMED hard against the stops in a full left turn. The wheels did not gently turn to the stops, they literally SLAMMED over.
Since then, if the situation arises where I must back up with a toad, I have disconnected the toad, moved it, moved the towing vehicle, reconnected, and gone on my way.
I was by myself, so there was no one available to hold the steering wheel. The way the wheels moved, that is probably a good thing. Any body trying to hold the wheel just might have ended up with broken bones!
Yes, some say they do it all the time. Good for them. Personally, I will never try it again. I had one educational experience, that is enough for me!
