Description

The RVGC Gooseneck Coupler is a non-cushioned, one-piece product that replaces the existing kingpin box on a 5th wheel camper. It bolts into the same bolt holes, allowing the camper to be towed by a gooseneck ball. It has a rating of 24,000 lbs and a tongue weight rating of 6,500 lbs. The RVGC-A is an adjustable version, offering 4 inches of adjustment at the coupler, with most trailer manufacturers providing an additional 3 inches of adjustment in their hole patterns, for a total of approximately 7 inches of adjustment. Bolt hole location and number of holes vary depending on the current pin box model on the unit. This product is made in America.
