Description

The RVGC Gooseneck Coupler allows you to tow your 5th wheel camper with a Gooseneck ball without an adapter. This one-piece unit bolts into existing king pin box bolt holes after unbolting the original. It is rated for 24,000 lbs Gross Trailer Weight and a 6,500 lbs Tongue Weight. The adjustable version (RVGC-A) provides 4″ of adjustment at the coupler, plus an additional 3″ from most trailer manufacturers' adjustable hole patterns, totaling approximately 7″ of adjustment. Bolt hole location and number of holes vary based on the current pin box model.
