The B&W Companion RVK3500 is a premium fifth-wheel hitch engineered for RV owners who demand the smoothest and most stable towing experience. Built around B&W’s renowned Turnoverball under-bed mounting system, it allows you to tow a fifth-wheel or switch to a gooseneck setup using the same base—without giving up strength or convenience.
Its fully articulating head pivots both front-to-back and side-to-side, helping your trailer track smoothly over uneven roads and angled campsites. The cam-action latching handle makes uncoupling effortless, even when the truck and trailer aren’t perfectly aligned. Polyurethane bushings absorb shock and eliminate metal-on-metal contact, giving you a quieter, rattle-free ride.
With a 20,000 lb gross trailer weight rating and 5,000 lb vertical tongue weight rating, the Companion delivers the robust towing capability needed for large fifth-wheels. Made in the USA and backed by a limited lifetime warranty, it’s built to perform year after year. The RVK3500 ships in two boxes (RVB3500 base and RVC3006 coupler) and installs cleanly with no bed invasion.
