B&W in bed trailer hitch for fifth wheel gooseneck trailers. The base is installed already all you have to do is mount it in the bed of your truck. Mounting rails, bolts, and tripod to hold the trailer while it is not on your truck are all included. 20,000lb capacity made in the U.S.A. The mounting holes on the base of the hitch are 13" × 30" measuring from the center of the bolt holes. This is a great find for someone I have more in it but I am not using gooseneck trailers anymore and this receiver is sitting in the corner of my shop. Asking $400 or best offer and I do have a few more pictures if interested
