What Todd Z said...pay attention, don't make sudden moves with the steering wheel, remember to allow extra room for turns (especially right turns) and try to avoid having to back in anywhere. My ST has a standard 2-inch receiver with a 2-inch ball, handles anything from my local rent-all place that I need to pull.
If you do have to go in reverse, remember to turn the wheel OPPOSITE of the direction you want the back of the trailer to go. Sounds screwy, but that is how it goes. If that is confusing, the trick I was taught was to steer with your hand on the bottom of the steering wheel, not the top. If you keep your hand on the bottom, then you move your hand in the SAME direction as you want the back of the trailer to go. Makes it a little easier. Oh, and while backing up, don't be shy about stopping and pulling forward a bit to try again if needed....better to take a couple extra minutes and look like a rookie then to ding up the trailer and have to pay damages or ding up your house, garage, or fence. Or worse, another vehicle.
