If you want to run a B&W 5th wheel hitch in a truck that does not have a factory-drilled bed or a proprietary OEM rail system, the RVK2605 Universal Mounting Rail is the starting point. This heavy-duty rail kit gives you the proper fore-aft and lateral positioning anchors so your hitch head sits exactly where it needs to be -- centered over the rear axle, level, and locked down. At 67 lbs and spanning 44.75 inches, this is a purpose-built structural component, not a universal bracket improvisation.
B&W Hitches has built its reputation on tight tolerances and over-engineered mounting solutions. The RVK2605 Universal Mounting Rail is part of that same philosophy -- designed to work across a broad range of full-size truck beds while maintaining the structural integrity that heavy 5th wheel towing demands. Whether you are towing a lightweight toy hauler or a heavy triple-slide diesel pusher-style 5th wheel, the foundation has to be right.
The "Universal" designation means this rail is engineered to fit the most common full-size truck bed configurations -- GM, Ford, Ram, Toyota Tundra, and Nissan Titan -- without requiring bed drilling in most applications. The rail system anchors into the factory stake pocket holes or bed frame channels, depending on the truck, providing a clean, no-drill or minimal-drill installation path.
At 67 lbs, this is a substantial steel rail system built to handle the dynamic loads of 5th wheel towing over long hauls and rough roads.
The 44.75" rail length positions your hitch head correctly across the width of a standard full-size truck bed for proper kingpin capture.
Designed to fit most full-size domestic and import trucks using stake pocket or frame-channel anchor points -- no specialty bed required.
Engineered as a base component for B&W 5th wheel hitch heads, including the Companion and Turnoverball-adjacent product lines that use rail-mount configurations.
The RVK2605 is the mounting rail assembly only. It does not include a hitch head, jaw assembly, or kingpin coupler. If you are building out a complete 5th wheel towing setup, you will pair this rail with a compatible B&W hitch head separately. This separation of components lets you select the correct hitch head for your trailer's pin weight and your personal preference for slider vs. fixed vs. pivoting head designs.
The RVK2605 Universal Mounting Rail is designed to work with the following truck platforms (short bed and standard/long bed configurations where applicable):
Always verify your specific model year and bed configuration against B&W's fit guide before ordering. Certain bed liner types (spray-in vs. drop-in) and factory bed accessories (cross-rails, cargo management systems) may affect installation clearance.
The RVK2605 installs into the truck bed using the stake pocket brackets or frame-rail attachment hardware included with the kit. The rails run laterally (side to side) across the bed, positioned over the rear axle centerline. B&W's design centers the rail span at 44.75 inches to align with the industry-standard kingpin capture zone used by most 5th wheel trailer manufacturers.
Installation is a one-person job with basic hand tools in most cases, though having a second person to hold the rail during initial positioning speeds up the process. No welding or specialty fabrication is required.
B&W Hitches, based in Humboldt, Kansas, manufactures its hitches and mounting hardware in the United States. The company is known in the RV and heavy-haul towing community for precision machining and hardware that does not loosen, flex, or fail under sustained heavy loads. The RVK2605 is consistent with that standard -- this is not a lightweight import rail, as the 67 lb shipping weight reflects the actual steel mass going into your truck bed.
