<h3>About B&W Trailer Hitches</h3><p><strong>B&amp;W Trailer Hitches</strong> has been engineering and manufacturing premium towing products in Humboldt, Kansas since 1987. <a href="/1442-bw">B&amp;W</a> was founded with a focus on building exceptional truck beds, but it was an early breakthrough in gooseneck hitch design that truly put the brand on the map. Within a year of opening its doors, B&amp;W introduced the Turnoverball Gooseneck Hitch — a revolutionary under-bed mounting system that bolted directly to the truck frame using existing holes, requiring no bed removal, drilling, or welding. That same clean-bed philosophy still defines every product the company makes today.</p><p><a href="/1442-bw-fifth-wheel-trailer-hitch-15606">B&amp;W fifth wheel hitches</a> are among the most trusted in the industry. The flagship Companion Fifth Wheel Hitch builds directly on the Turnoverball platform, sharing the same discreet under-bed mounting system so truck owners can tow a fifth wheel or a gooseneck with a single setup. When not towing, the Companion removes completely — leaving a clean, unobstructed truck bed. It features fully articulating jaws that pivot in four directions, polyurethane bushings for a quiet, rattle-free ride, and a cam-actuated handle that prevents accidental release. The result is a hitch engineered for both safety and everyday convenience.</p><p>For trucks equipped with factory OEM puck systems, B&amp;W offers a full range of <a href="/1442-bw-fifth-wheel-trailer-hitch-base-assembly-20218">fifth wheel hitch base assemblies</a> designed to mate seamlessly with the factory platforms found in Ford, GM, and Ram HD trucks. These purpose-built bases bring the same Companion coupler head — proven over years of hard use — to truck owners who prefer to leverage their factory prep packages.</p><p>Beyond fifth wheel and gooseneck products, B&amp;W's lineup extends to the Tow &amp; Stow Adjustable Ball Mount, which accommodates multiple ball sizes and stows neatly under the vehicle, and the Continuum Weight Distribution Hitch for balanced, controlled towing of heavy loads. Every B&amp;W product is manufactured using American-made materials right in Humboldt, Kansas, reflecting the brand's long-standing commitment to domestic craftsmanship.</p><h3>Why Truck Owners Trust B&W</h3><ul style="list-style:disc"><li><strong>American-made quality:</strong> All products are built in Humboldt, Kansas using domestic materials and precision manufacturing.</li><li><strong>Clean-bed design:</strong> B&amp;W's under-bed mounting philosophy keeps your truck bed usable when you're not towing — a concept they pioneered and that the industry widely adopted.</li><li><strong>Versatile systems:</strong> One Turnoverball mounting system supports gooseneck towing, fifth wheel towing, and a growing family of accessories.</li><li><strong>Proven durability:</strong> B&amp;W hitches are tested for both strength and durability and meet current industry standards for fifth wheel and gooseneck applications.</li><li><strong>Reader-recognized excellence:</strong> The Companion Fifth Wheel Hitch has been voted the favorite fifth wheel hitch by <em>RV Magazine</em> readers multiple years running.</li></ul>

This base unit is part of B&W's acclaimed Companion series, engineered to eliminate hitch sloppiness and provide a smooth, cushioned ride free of jerking.

Easy checkout process

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

Easy to search, buy and pay. Now to see how fast shipping is

Hope it works
