Choosing a B&W Companion fifth wheel hitch is mainly a compatibility and capacity decision. The hitch must match the truck’s mounting system, whether that is a B&W Turnoverball base or a factory fifth-wheel puck setup. Its rating must also suit the loaded trailer, pin weight, truck payload, rear axle and tires. Bed length and trailer nose shape determine whether a fixed hitch provides enough cab clearance or whether a compatible slider is needed. Before towing, confirm that the base is locked, the kingpin is correctly captured, the trailer has adequate clearance, and the braking and electrical systems work. Those checks matter more than choosing a hitch by brand name alone.
The name Companion covers several mounting approaches rather than one universal fifth wheel hitch. The first question is how the hitch will attach to the truck. A Companion designed for a B&W Turnoverball system is intended for that B&W under-bed mounting arrangement. An OEM Companion configuration is designed around a compatible factory puck system. Those interfaces should not be treated as interchangeable.
An aftermarket gooseneck hitch from another manufacturer does not automatically make a truck suitable for a Turnoverball-mounted Companion. The base, locking mechanism, legs and attachment points all need to be designed to work together. Use the exact hitch model and truck fitment information rather than relying on the truck’s make, the presence of a gooseneck ball or a similar-looking mounting plate.
The trailer matters just as much. Check its kingpin and pin box arrangement, loaded weight, pin load, front overhang and clearance around the truck bed. A hitch can be correctly installed and still be a poor choice if the trailer exceeds the truck’s payload or cannot turn without contacting the cab or bed rails.
Once the truck interface is known, compare the available Companion approach with the way you use the vehicle. The most suitable option is the one that fits the truck without adapters of uncertain compatibility and provides enough capacity and clearance for the trailer.
| Companion setup | Truck interface | Best suited to | Important limitation |
|---|---|---|---|
| Turnoverball-mounted Companion | A compatible B&W Turnoverball system | Owners whose truck already has the matching B&W under-bed gooseneck base | It should not be assumed to fit an unrelated gooseneck hitch or base |
| OEM Companion configuration | A compatible factory fifth-wheel puck system | Trucks equipped with manufacturer-installed fifth-wheel preparation | Puck spacing, legs and fitment vary by truck application, so the exact model matters |
| Companion slider configuration | A compatible Companion mounting arrangement on a short-bed application | Drivers who need additional maneuvering clearance between the trailer and cab | It adds operating steps and does not remove the need to check clearance and locking position |
The first two rows solve different mounting problems. A truck with factory pucks is not automatically equipped for a Turnoverball-mounted hitch, and a truck with an aftermarket gooseneck system is not automatically suitable for an OEM puck model. Check the current B&W fitment information for the truck and the hitch model before ordering.
A hitch rating is only one part of the calculation. The trailer’s loaded weight must remain within the limits of the hitch, truck, axles, tires and trailer. A high-rated B&W Companion cannot increase the payload or rear-axle capacity of the truck carrying it.
Gather the following information before making a decision:
Do not select a hitch by comparing its advertised capacity with the trailer’s dry weight. Dry weight usually excludes much of the equipment and cargo added before a trip. If the actual loaded weight is unknown, using the trailer’s GVWR for conservative planning is safer than treating the empty specification as the expected travel weight.
Clearance is one of the most important parts of a B&W Companion installation. A long-bed truck generally provides more room between the fifth wheel pivot and the cab, but it still needs to be checked. A short-bed truck may need a slider or another manufacturer-approved clearance solution, depending on the trailer’s front cap, pin box and turning geometry.
Do not judge clearance only with the truck and trailer parked straight on level ground. Check the space around the trailer’s front corners, the cab, bed rails, tailgate and hitch head. Turning on uneven ground can change the relationship between the trailer and truck, and suspension movement can reduce clearance that appeared sufficient when stationary.
Hitch height also affects the result. The goal is to establish a suitable towing attitude while preserving clearance above the bed rails and keeping the truck and trailer within their permitted operating positions. Raising the hitch to solve one clearance issue can create another by altering trailer attitude, axle loading or the available space at the front of the bed.
A slider can move the hitch rearward for low-speed maneuvering in a compatible application. It is not permission to turn to any angle without checking the trailer, and it should not be left in an incorrect or unlocked position for road travel. Follow the specific slider’s operating instructions and confirm the mechanism is locked in the position required for the next part of the trip.
Installation should follow the instructions for the exact B&W Companion model and the truck’s mounting system. The following process is a useful verification sequence, but it does not replace the manufacturer’s manual or the required torque values.
Keep the landing gear supporting the trailer until the hitch connection has been checked and the controlled test confirms that the truck and trailer are properly coupled. If the jaw does not close correctly, the handle will not reach its required position or the kingpin cannot be inspected, stop and resolve the problem before moving the combination.
A first installation needs detailed attention, but a secure setup can still be compromised during loading, maintenance or hitching. Use a short check before every trip:
Changing hitch brands will not correct an overloaded truck or an unsuitable trailer shape. If the B&W Companion cannot meet the mounting, capacity and clearance requirements, the safer alternative may be a different hitch configuration or a tow vehicle with the necessary limits.
No. Companion models and bases are designed for particular truck mounting systems, bed lengths and applications. Confirm the exact truck, mounting interface and hitch model before buying or combining components.
You should not assume that. A Turnoverball-mounted Companion is designed around the compatible B&W system, so an unrelated gooseneck hitch may not provide the required attachment or locking arrangement.
Not always, because clearance depends on the truck, hitch position, trailer front cap, pin box and turning conditions. A slider may provide useful maneuvering room, but the actual combination still needs to be checked and the slider operated exactly as instructed.
The selected hitch must be suitable for the trailer load, but the hitch rating is not the only limit. The truck’s payload, rear axle, tires, towing rating and combined rating must also accommodate the loaded trailer and pin weight.
Use the coupling procedure for the exact hitch model, including the required handle or indicator position and a visual inspection of the locking mechanism around the kingpin. Complete the recommended pull test before retracting the landing gear or beginning the trip.
No. The hitch transfers the trailer load to the truck; it does not increase the truck’s payload, axle or tire capacity. If the pin load exceeds the available limits, the solution is to reduce the load, use a suitable trailer and hitch combination, or choose a truck with greater capacity.
Before towing, treat the B&W Companion fifth wheel hitch as one part of a complete system. Match the mounting interface, use the loaded trailer weight, verify payload and axle limits, establish cab and bed clearance, and confirm the hitch and kingpin are locked. If any of those checks remains uncertain, resolve it before the trailer leaves the driveway.
