There are two basic types of dolly's. One has a swivel pan thrus the steering wheel must be secured straight ahead.
The other does not have a swivel pan so the steering wheel must be able to move freely.
As with everything there are haters of both systems. I personally use the Acme EZTow which is a non swivel pan dolly. Works great for me.
