Axtually, I have not even gotten close, and I have had the trailer for almost 2 years. If you are used to a bumper pull that can also jackknife and damage your vehicle, you won’t have a problem. I am always watching how much I tightly jackknife, but it is pretty rare that you need to go that tight anyway.
I was riding with a person with a full size truck bed, and she was showing me how great a gooseneck was. tried to turn it around on a 2 lane country road. Well, it ended up being so tight almost into one of the side ditches, that she had to jackknife and did major damage to the truck, high up, just behnd the driver’s door - really crunched it in. No truck is safe if you don’t pay attention, except for those turnaround rigs. Then you just turn to face the trailer, and drive forward.
