Alright the key to gettin it right is a good setup. Now, this is alil something i go by and it works everytime. All you really gotta do is learn how to drive the trailer. Next step is to not over steer, when you are backing to the cones. A gentle turn to the right or left slow is all you need to get it where you want it. You dont have to cut it sharp left to right until you get to the cone and you gotta cut it hard to the right to get it in there THATS THE ONLY TIME YOU CUT IT HARD. The key to backing is to creep back there to it, you dont have to be in a rush and speed back there. The slower you going back the more time you give to trailer to react to the turn( it take the trl 5 to 6 feet to react). Now the funtmental to driving the trailer. if you turn right you will notice the trailer tendem stop and all it is doing is sliding left and when you turn left you see the trailer tendem tire roll again. So when you want the trailer to go to the left turn the steering wheel alil to the right till you see the trailer wheel stop and start sliding to the left. When you get it to where you want it, just slowly turn it back to the left till you see the trailer tendem wheel rollin again. You just repeat that until you get it back to the dock.Thats all it is, all you gotta do is just learn how to drive the trailer. thats why they call it a combination vehicle cause you driving two things, but just follow this and practice i guarteed that you will be knockin it out in no time
