Superglide SuperRail mounting kit and Superglide

[johndeerefarmer]

Is anyone running the Superglide SuperRail mounting kit which lets you mount the Superglide to a B&W gooseneck hitch? If so how do you like it?
It seems to be the best option for me to free up the bed in front of the wheel wheels for my generator as well as giving me a flat bed when I remove it.
The Kurt X5 doesn't appear as sturdy and it appears that the Superglide will not fit it.

Thanks
