B&W Hitches Patriot Series 5th Wheel Mounting Rails B&W Hitches RVR3210 Patriot 5th Wheel Hitch Mounting Rails

The foundation of a solid 5th wheel towing setup starts with the right rails. The B&W Hitches RVR3210 Patriot Mounting Rails give you a direct-fit base for the B&W Patriot 5th wheel hitch system, sized at 44.75 inches long and built from heavy-gauge steel to handle serious towing loads. Whether you are replacing worn or bent rails, outfitting a new truck bed, or building a complete Patriot hitch installation from the ground up, these rails are the structural backbone that everything else mounts to. Note that hardware is NOT included with this set -- fasteners, U-bolts, and any bed mounting hardware must be sourced separately or are available in the matching B&W hardware kit for your specific truck.

Heavy-Duty Rails Engineered for the B&W Patriot Hitch System

B&W Hitches built its reputation on precision-fit towing products made in the USA. The Patriot series is their dedicated 5th wheel hitch line, designed specifically for pickup truck beds with standard mounting rail channels. The RVR3210 rails are the structural component that anchors the entire Patriot hitch to your truck -- getting this right matters more than almost any other part of the installation.

At 44.75 inches in length, these rails span a typical full-size pickup truck bed from side to side with proper clearance, allowing the Patriot hitch head to sit centered and level for predictable, stable towing. The 40-pound weight of the rail pair reflects the heavy-gauge steel construction -- these are not lightweight stamped parts.

Patriot Series Fit

Designed specifically as mounting rails for the B&W Patriot 5th wheel hitch family, ensuring correct geometry and hitch head alignment.

Heavy-Gauge Steel

40 lbs. of steel rail construction -- built to withstand the lateral and vertical forces of 5th wheel towing over the long haul.

44.75 In. Rail Length

Engineered to span the full width of a standard full-size pickup bed, providing correct mounting spread for the Patriot hitch head.

Replacement or New Install

Works as a direct replacement for damaged Patriot rails or as the foundation for a new complete Patriot 5th wheel hitch installation.

Where the RVR3210 Fits in the B&W Patriot Lineup

The B&W Patriot hitch system is a modular 5th wheel hitch platform. The major components are sold and sometimes replaced individually: the hitch head assembly, the mounting legs or towers, and these mounting rails. The RVR3210 rails are the lowest layer -- they sit in the truck bed and are bolted down through the bed floor or to existing rail mounts, and the hitch legs attach to them.

If you are purchasing the Patriot hitch head (such as the RVK2400 or RVB3500 series) without a bundled rail kit, or if your existing rails were damaged during an accident or heavy use, the RVR3210 is the correct replacement rail set to restore a complete, functional installation.

Replacement Rails Made Right
Replacing bent, cracked, or corroded mounting rails restores the full structural integrity of your 5th wheel hitch installation. Using OEM B&W rails ensures the mounting geometry, hole patterns, and leg attachment points match exactly what the Patriot hitch head expects.

Hardware Not Included -- What You Will Need

The RVR3210 ships as rails only. Depending on your truck and installation method, you will also need:

  • Bed mounting hardware (U-bolts or frame brackets specific to your truck make and model year)
  • Leg attachment bolts and lock hardware for connecting the Patriot hitch legs to the rails
  • Any truck-specific rail adapter kit if your bed does not have pre-punched mounting holes

B&W offers truck-specific hardware kits (sold separately) that pair with these rails for most common full-size pickups from Ford, GM, Ram, and Toyota. Match your hardware kit to your truck year, make, and model before ordering to ensure a complete installation.

Truck-Specific Hardware Kits Available
B&W offers model-specific mounting hardware kits for major full-size pickup platforms. These rails must be paired with the correct hardware kit for your truck -- the RVR3210 rails provide the structural base, but the bed-mount fasteners come from the separate hardware kit.

Installation Overview

Installing the RVR3210 rails requires placing them crosswise in the truck bed at the correct fore-aft position relative to the rear axle centerline -- typically 1 to 2 inches forward of the rear axle for 5th wheel hitches. The rails are then anchored through the bed floor to the truck frame using the appropriate hardware kit. Once secured, the Patriot hitch leg assemblies bolt to the rail channels, and the hitch head drops onto the legs.

A torque wrench and basic hand tools are required. Two people make positioning and initial bolt-up much easier given the 40 lb. combined weight of the rail pair.

Installation Tip
Before tightening rails to final torque, dry-fit the hitch legs and head to confirm the kingpin capture height is appropriate for your trailer. Adjust fore-aft rail position if needed before final torque. Re-torque all hardware after the first 500 miles of towing.

Compatibility Notes

The RVR3210 mounting rails are designed for use with the B&W Patriot 5th wheel hitch system. They are not cross-compatible with rails from other hitch brands such as Reese, Curt, or PullRite, as leg mounting hole patterns and channel dimensions differ between manufacturers. Always verify rail and leg compatibility within the B&W Patriot system before ordering.

Verify Fitment Before Installing
These rails are engineered for use with B&W Patriot series 5th wheel hitches. Using non-Patriot hitch legs or head assemblies with these rails may result in improper fit, misalignment, or unsafe towing conditions. Confirm your complete hitch assembly is B&W Patriot compatible.

Important Information -- Read Before Ordering
  • Hardware is NOT included with the RVR3210. You must purchase a compatible truck-specific hardware kit separately to complete the installation. Rails alone cannot be mounted to your truck without the appropriate fasteners and brackets.
  • These rails are designed exclusively for the B&W Patriot 5th wheel hitch system. They are not compatible with hitch heads, legs, or hardware from other manufacturers.
  • Confirm your truck's bed dimensions and mounting hole pattern are compatible before installing. Certain short-bed trucks may require additional B&W accessories for safe 5th wheel clearance during tight turns.
  • All mounting hardware should be torqued to B&W Patriot specifications. Re-torque after the first 500 miles of towing to account for initial settling.
  • Inspect rails, fasteners, and all mounting points before every towing season and after any heavy towing event or impact.
  • Do not exceed the tow rating of your truck or the Patriot hitch head assembly, regardless of rail capacity. The weakest link in the system sets the effective tow limit.
