I've pulled lots of trailers, goose necks, 5th wheels, bumper pulls. Currently have gooseneck horse trailer, 5th wheel travel trailer w/ gooseneck adapter. Wouldn't change a thing. The 5th wheel/gooseneck is by far the best way to pull a trailer. And I like to pull them with a diesel (Ford F350, SRW). I've never heard anybody pulling complain about too much spring or too much power, FWIW. I don't like dual rear wheels, have never seen the need.
