Fifth wheel hitches are not built for the additional stress on the hitch framework added by use of a Goosebox. It is inadvisable and I wonder if some fifth wheel manufacturers might void a warranty if they were aware it was towed with a Goosebox.
Compare the structure of the goose neck of a farm truck with the hitch structure of a fifth wheel. The Gooseneck trailer was designed for that type of hitch. Fifth wheels are not. I was once shopping for a specific model of used fifth wheel, found one, and saw it had a Goosebox, so I passed on it. If the hitch structure were damaged by use of the Goosebox, in most cases the damage might not be visible, thus you would have to dismantle the fifth wheel hitch to find out.
Use at your own risk.
I wouldn't consider it if it voided the frame warranty. Lippert does approve the use of them. Goosebox is not a goose extension.
