<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>

Product Details

The B&W RVB3405 Companion Slider Base is the foundation of the Companion Slider 5th wheel hitch system, designed to work with the B&W Turnoverball under-bed gooseneck mounting system. This slider base provides 12 inches of lateral movement for enhanced maneuverability in short-bed trucks, allowing you to navigate tight corners without cab contact.

Key Features:

  • Engineered slider mechanism provides 12 inches of travel for turning clearance
  • Utilizes B&W Turnoverball under-bed mounting system (sold separately)
  • Polyurethane bushings eliminate metal-to-metal contact for a smooth, rattle-free towing experience
  • Tight tolerances ensure smooth sliding action without sloppiness
  • Can be removed for a clean, level truck bed with no mounting rails
  • Powder-coated steel construction for durability and corrosion resistance
  • Made in the USA (Humboldt, Kansas)

Capacity Ratings:

  • Gross Towing Weight (GTW): 20,000 lbs
  • Vertical Tongue Weight (VTW): 5,000 lbs

Important Notes:

  • This is the base unit only - coupler head sold separately (requires RVC3006 or compatible Companion coupler)
  • Requires B&W Turnoverball gooseneck hitch for installation
  • Complete kit part number is RVK3405 (includes base and coupler)
  • Backed by B&W's limited lifetime warranty

The RVB3405 slider base combines the versatility of the B&W Turnoverball system with the precision engineering of the Companion series, allowing you to tow both 5th wheel and gooseneck trailers with the same mounting system.
