Wingnut60 I have been pulling fifth wheel trailers with a gooseneck converter for years,the thing I liked about the star performance hitch is the ability to obsorb the chucking motion or back and forth movement felt in the truck by the occupants as the trailer supension works up and down.Doug at sphitch.com now has a fifth wheel setup with that should be great. Check out his web site sphitch.com.Also look at the link below on the glide ride,they will describe it better than I can.

Here is a link to a magazine article that lead me to sphitch.com.
