<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>

The B&W RVB3705 is a heavy-duty 25,000 lb capacity hitch base designed specifically for 2016-2019 GM trucks equipped with the factory puck system. This base component is engineered to work exclusively with the B&W Companion OEM 5th wheel hitch system, providing a secure foundation for your fifth wheel towing needs.

Key Features:

  • 25,000 lb gross towing weight capacity for heavy-duty fifth wheel trailers
  • Custom-fit design for 2016-2019 GM trucks with factory puck system
  • Direct bolt-in installation using existing puck mount points
  • Durable powder-coated finish for corrosion resistance
