B&W RVB3770 Companion Slider Fifth Wheel Hitch Base for GM OEM Puck System

Manufacturer

B&W

<p>Founded in 1987 in Humboldt, Kansas, by Roger Baker and Joe Works, B&W Trailer Hitches has built a reputation as one of America's most trusted names in towing solutions. What began as a partnership between a classic car restorer and a farmer facing tough economic times evolved into an industry-changing success story. The company remains one of the last hitch makers manufacturing in America, producing all their products in a nearly 600,000-square-foot facility in the heartland.</p> <h3>Revolutionary Gooseneck Hitch Innovation</h3> <p>B&W recognized a way to remove the inconvenience of a gooseneck ball permanently welded in truck beds, designing a hitch with mounting hardware underneath the bed and a ball that turned over and stowed in place—the Turnoverball Gooseneck Hitch. This innovation fundamentally changed the industry. Today nearly every gooseneck manufacturer uses this type of ball storage and mounting system. The <a href="/1442-bw-gooseneck-trailer-hitch-kit-17978">Gooseneck Trailer Hitch Kit</a> allows truck owners to enjoy a completely level, functional truck bed when not towing—no obstructions, no permanent installations limiting bed space.</p> <p>The underbed mounting system bolts to already existing holes in the frame, requiring only a 4" hole in the truck bed. This means no welding, no extensive drilling through the frame, and no need to remove the truck bed during installation. The result is a clean, professional installation that maintains the truck's structural integrity while delivering exceptional towing capacity.</p> <h3>Fifth Wheel Excellence</h3> <p>A few years after their gooseneck breakthrough, B&W applied the same concepts to fifth-wheel hitches, using the same under-bed mounting hardware with a Companion design featuring single-point attachment that was removable when not towing. The <a href="/1442-bw-fifth-wheel-trailer-hitch-15606">Fifth Wheel Trailer Hitch</a> line showcases B&W's commitment to versatility and user-friendly design. What makes the system particularly clever is its compatibility—the Turnoverball mounting system can accommodate both gooseneck and fifth wheel applications, giving truck owners maximum flexibility for different towing needs.</p> <p>The <a href="/1442-bw-fifth-wheel-trailer-hitch-base-assembly-20218">Fifth Wheel Trailer Hitch Base Assembly</a> components are engineered for smooth, quiet operation. The Companion was designed to provide a quiet and smooth ride for the user, addressing common complaints about road noise and vibration that plague lesser fifth wheel hitches.</p> <h3>Weight Distribution and Pintle Hook Solutions</h3> <p>Beyond their signature gooseneck and fifth wheel products, B&W offers comprehensive towing solutions. The <a href="/1442-bw-trailer-weight-distribution-kit-48263">Trailer Weight Distribution Kit</a> ensures proper load distribution for safer, more stable towing with bumper-pull trailers. These systems help prevent trailer sway, reduce stress on the tow vehicle, and improve overall handling—critical factors when hauling heavy loads over long distances.</p> <p>For heavy-duty commercial and agricultural applications, the <a href="/1442-bw-pintle-hook-trailer-hitch-15153">Pintle Hook Trailer Hitch</a> offerings deliver the rugged reliability needed for extreme towing conditions. Pintle hitches excel in off-road environments and applications requiring maximum articulation between truck and trailer.</p> <h3>American Manufacturing and Quality Standards</h3> <p>B&W gets their steel straight from the American Heartland, where it is forged in mills they know and trust. This commitment to domestic materials and manufacturing allows the company to oversee every detail of production. In 2007, ownership began transferring to the company's employee-owners, creating a workforce with a direct stake in maintaining the quality and innovation that built the brand's reputation.</p> <p>B&W kept solving problems other hitch manufacturers weren't, always thinking of the customer's towing experience. Whether you're hauling livestock trailers, construction equipment, recreational vehicles, or heavy cargo, B&W's engineering focuses on real-world towing challenges—from installation simplicity to bed accessibility, from towing stability to long-term durability. Their products are tested to meet the latest industry standards, backed by limited lifetime warranties, and trusted by professional haulers and weekend adventurers alike.</p>

so far, so good. a little vague as to model compatibility, but we'll hope for the best. I don't want to have to make a return.

great web site easy to order .. Now we will see about the shipping time ??

Easy and found what I was looking for

gorgious

On drivers side, tube was contacting the body trim (2014 Toyota Access cab) after torqueing the bolts. Gap between body and tube was not uniform. Added small shim at center mount and approximately 1/4 inch shim in the front to achieve clearance and uniform gap. Longer bolt required. Right side installed perfect with no issues.

very easy to find what I was looking for and excellent descriptions of product.

Would Buy From Company Again
