My Toad has 2 ACC key positions. One locks the wheel the other does not. AND it is very easy to be in the wrong one.
To this day even after 5 years of towing it I always set it all up and then turn the wheel all the way one way and then all the way the other way to MAKE SURE the steering wheel is not going to lock on my first turn with it.
Been there done that right from the RV dealership install because they had the key in the first ACC position and not the second one that prevents the wheel from locking upon the first turn.
