That's the case with my 773 also. I have a gooseneck trailer and with the steel tracks we have to be careful to load the Bobcat only when the trailer is level both ways. Believe me, with the steel tracks, and an unlevel dovetail trailer, the Bobcat will slide off. This happened to my son the first time he loaded it on our trailer, and it wasn't a pleasant experience. He was loading the Bobcat at a jobsite and the road the trailer was parked on made the trailer have a slight tilt to the side and to the rear. So when he was driving it up on the trailer and when it was on the dovetail, it started sliding. It went off the rear corner and just laid over. He was ok and it didn't damage the Bobcat, but after about three months now, he's just feeling comfortable about loading it on the trailer again. But now, he definitely checks to make sure the trailer is level before loading. So be "careful" if you have steel tracks when loading the Bobcat onto a gooseneck trailer with a dovetail.
