Convert-A-Goose 5th wheel base plate for gooseneck hitches. We have introduced this because of customer request for other options. If you have a Turnover ball by B&W Trailer Hitches then we have a Convert-A-Goose for you. With a GVWR of 20,000 lbs you can pull just about any 5th wheel. The universal rail slots on the base plate will fit most 5th wheel units on the market today. Simply remove the ball in your hitch, slide the post into place and lock it back into position. Lay the base plate over the post and tighten down. It’s really that easy. NO bed rails, NO drilling holes, and much lighter at only 60 lbs.
