I change back and forth between gooseneck and my B&W. It is a bit of a pain but there are some advantages of using the B&W.
!. No need for safety chains with the B&W.
2 The Goose Box puts added torque on the frame of the fifth wheel trailer. Some trailers have week frames and this could end up being an issue on those trailers.
3. The B&W is a little nicer to couple and uncouple than a ball type set up.
4. If you buy a fifth wheel hitch for your truck your set to hall any gooseneck or fifth wheel type trailer.
