The Bulldog Gooseneck-to-5th-Wheel Trailer Coupler Adapter # BD0289640300 will fit a gooseneck trailer of up to 25,000-lbs gross weight that takes a 4-inch diameter inner tube.

The wiring on a semi is not normally the same as a standard RV or Gooseneck trailer. You will need to use a couple different harnesses to get what you are looking for. I recommend the ZCI Circuit Protected Vehicle Wiring Harness w/ 4-Pole Flat…
