I should mention that some cars - like my 2013 SMART require that the steering wheel be "tensed" by a bungee cord that will hold the wheel in the straight ahead position.
If the bungee is there, the steering wheels turn appropriately. If it's not there they will oscillate back and forth lock-to-lock. A very bad thing. I've been told it has something to do with the wheel base length. It doesn't make a lot of sense to me. Conversely you don't want the bungee cord if you don't need it.
I suggest the first time you tow it, do so in a large empty parking lot with someone in the drivers seat with a live telephone call going on to the motorhome driver. A few low speed passes with turns through the parking lot should be enough to build confidence the car will tow without any additional help.
