The B&W Trailer Hitches Turnoverball Gooseneck Hitch GM 2500/3500 is a great quality hitch when you need it, and a level bed when you don't. With no drilling, welding or bed removal required, this hitch installs easily and completely underneath the bed of the truck. All bolts fit to only existing holes in the frame. The hitch requires only a 4-inch hole in the bed for the ball to come through, and 4 other small holes for hooks on both sides of the hitch. Included is a flexible latch pin handle attached to a spring-loaded, 5/8" steel locking pin that goes completely through the ball for extra assurance. With a 30,000 lb carrying capacity, you will be able to tow just about any trailer including travel trailers.
