I have a 2010 Fuzion FZ383 Toy hauler 40 f00t 3 axles. I had a Flatbed installed on my F450 Ford. Because it set to tall I went with a gooseneck adapter to pull with. Long story made short after 2 yea...
The potential danger of using a gooseneck adapter has been discussed frequently here. Obviously there is an increase of torque forces applied to the pin box when using one. And some trailer manufacturers will void the warranty if you use one. But a lot of folks have used them for years with no "apparent" problem. I say apparent as there could be as yet unseen damages occurring. So just a matter of chance I guess. Just be glad it was the pin box and not the frame.
