Using a Parkit360 trailer dolly couldn't be easier. Just switch the Unit into Freewheel Mode (Neutral) to wheel it to your trailer effortlessly. After engaging the motor and connecting the hitch, it's simply a matter of using the forward/reverse toggle switch to steer. The user faces the trailer while parking and can see where it is at all times—down to a fraction of an inch—something that's nearly impossible to accomplish with a vehicle.
