B&W Companion: Best Overall Fifth Wheel Hitch
The B&W Companion has earned an iconic reputation among full-time RVers for eliminating “chucking”‚Äîthe annoying back-and-forth jerking motion felt during acceleration and braking. It achieves this smooth ride through a heavy-duty dual-jaw design that wraps completely around the trailer kingpin. By offering a wrap-around jaw with tight tolerances, the physical play between the truck and trailer is virtually eliminated.
The engineering behind this hitch focuses heavily on shock absorption and quiet operation. It features a fully articulating head that moves in multiple directions, supported by polyurethane bushings that act as dampeners. Additionally, it mounts to the B&W under-bed turnover ball system, leaving your truck bed completely flat and usable when the hitch is removed.
The primary tradeoff of this premium build is its physical weight. This hitch is a solid steel beast, weighing in at over 130 pounds across its two main components. Removing it from the truck bed requires significant physical effort or a garage hoist system.
If you prioritize a premium, noise-free towing experience above all else and do not mind a heavy lifting job to clear your truck bed, the B&W Companion is the gold standard. It is built to outlast your truck and guarantees peace of mind on long-haul adventures.
Curt A20: Best Value for Heavy-Duty Towing
The Curt A20 targets heavy luxury fifth wheels without forcing you to pay a boutique price tag. Rated for up to 20,000 pounds of gross trailer weight, it features a highly durable cast steel head and interlocking jaws for secure coupling. It offers a premium feel at a price point that leaves room in your budget for other off-grid upgrades.
One of the most practical features of this hitch is its user-friendly indicator system. A three-position color-coded indicator, visible directly from the cab, shows the exact status of the coupling mechanism. This simple safety feature prevents dangerous high-pinning accidents, which can instantly crush truck bed rails during hookup.
While the built-in torsion springs provide a smooth ride, the hitch lacks some of the ultra-refined damping of hand-assembled premium competitors. It can feel a bit mechanical and stiff over rough bridge transitions and concrete expansion joints. However, the sheer strength and safety mechanisms make it highly reliable.
The Curt A20 is the ultimate choice for budget-conscious haulers towing heavy, full-time living rigs. It delivers commercial-grade strength and essential safety features without forcing you to pay a premium for brand prestige.
Andersen Ultimate Connection: Best Lightweight
The Andersen Ultimate Connection revolutionized the alternative living world by challenging traditional steel plate designs. Weighing under 40 pounds, this hitch utilizes a clever aircraft-grade aluminum pyramid structure. This radical design shift means a single person can install or remove the hitch in under five minutes.
Instead of a traditional fifth-wheel kingpin plate, the Andersen mounts to a standard gooseneck ball. It elevates the connection point and uses a funnel-shaped block adapter that mounts directly to the trailer kingpin. Coupling is incredibly easy because you have a massive visual target to drop the ball into, even if you are backing up at an angle.
There are some minor compromises to consider with this lightweight design. Because it shifts the physical pivot point and utilizes a kingpin adapter, some frame manufacturers have raised warranty questions in the past. Additionally, the base bolts must be torqued to precise specifications during every installation to prevent the pyramid frame from shifting in the truck bed.
For solo travelers, older RVers, or anyone who needs to quickly reclaim their truck bed for daily work, the Andersen Ultimate is unmatched. If you cannot lift 150 pounds of steel but still want to tow a large fifth wheel, this is your ticket to independence.
Reese M5: Best Choice for OEM Prep Packages
Modern heavy-duty trucks from Ford, GM, and Ram often arrive from the factory with under-bed towing puck systems. The Reese M5 is engineered specifically to drop directly into these factory prep packages without the need for heavy adapter rails. This direct connection ensures a lower profile and a cleaner aesthetic inside the truck bed.
The locking system utilizes an always-ready talon jaw that automatically wraps around the kingpin upon contact. This means you do not have to manually open the handle before backing the truck into the trailer. A highly visible indicator window built into the head confirms a secure lock with a simple glance.
The limitation of this highly integrated system is its lack of adaptability. An M5 configured for a Ford puck system cannot be easily converted to fit a GM or Ram truck if you switch tow vehicles down the road. It is a highly vehicle-specific tool designed for maximum efficiency with your current truck.
If you bought a modern truck equipped with a factory puck system and want a seamless, drop-in fit with zero assembly hassle, the Reese M5 is your ideal match. It maximizes your truck’s engineered towing points with minimal fuss.
Demco Recon: Best Versatile Lightweight Hitch
The Demco Recon bridges the gap between ultra-lightweight ball-mount systems and traditional heavy steel plate hitches. Weighing roughly 95 pounds and separating into two manageable pieces, it is exceptionally easy to handle. It offers the familiar security of a traditional wrap-around jaw without the spinal strain of a standard 150-pound hitch.
Versatility is the core strength of the Recon. Depending on the model you select, it can mount to industry-standard base rails, a gooseneck ball, or OEM puck systems. The wrap-around jaw design provides a incredibly secure lock on the kingpin, minimizing play and noise while traveling down uneven gravel roads.
Because of its lighter steel construction, it has a lower overall weight rating than some of its heavy-duty competitors, typically capping out at 21,000 pounds. It also lacks the advanced internal damping systems found in heavier premium models. You will feel slightly more road feedback, but the tradeoff in weight is often worth it.
The Demco Recon is perfect for owners of mid-profile fifth wheels who want a traditional jaw connection but refuse to strain their back during installation. It offers the physical manageability of a lightweight hitch without abandoning the classic physical hookup style.
PullRite SuperGlide: Best Automatic Slider
Standard short-bed trucks—typically 5.5 to 6.5 feet in length—risk serious damage during tight turns because the front cap of the trailer can collide with the truck cab. The PullRite SuperGlide solves this problem by automatically sliding backward along its base rails during turns. This dynamic movement happens seamlessly without requiring the driver to exit the vehicle.
Unlike manual sliders, which require you to stop, exit the truck, throw a lever, and lock the trailer brakes to slide the hitch, the SuperGlide handles the movement completely on the fly. This prevents costly “cab-crushing” accidents during sudden, unexpected U-turns or tight campsite maneuvers. It takes the guesswork and stress out of navigating tight fuel stations.
The primary downsides to this mechanical marvel are weight, complexity, and cost. It is an incredibly heavy, dense unit that requires a vehicle-specific capture plate attached to your trailer kingpin to function correctly. Additionally, the slide rails require frequent, meticulous lubrication to prevent binding and ensure smooth operation.
If you tow a large fifth wheel with a short-bed truck and want absolute, worry-free maneuvering in tight spaces, the PullRite SuperGlide is non-negotiable. It is an expensive insurance policy that pays for itself the very first time you avoid a shattered back window.
How to Choose Between Fixed and Slider Hitches
Choosing between a fixed and a slider hitch comes down to a careful calculation of truck bed space, maneuverability needs, and weight tolerances. Making the wrong choice can lead to a damaged truck cab or unnecessary physical labor.
- Truck Bed Length: Long beds (8 feet) use fixed hitches; short beds (5.5 to 6.5 feet) often require sliders.
- Trailer Nose Profile: Modern curved caps reduce the need for sliders, while flat-front vintage trailers demand them.
- Weight Tolerance: Sliders add 50 to 100 pounds of deadweight, reducing your available payload capacity.
Fixed hitches keep the trailer kingpin centered directly over or slightly ahead of the truck’s rear axle at all times. This is the optimal towing position for weight distribution and stability. It is the standard choice for long-bed trucks (8-foot beds) where cab clearance is never an issue.
Short-bed trucks do not have enough physical clearance between the cab and the front cap of the fifth wheel during sharp 90-degree turns. A slider hitch physically moves the connection point rearward toward the tailgate during low-speed maneuvering, creating the necessary clearance.
While manual sliders are budget-friendly, they require you to anticipate tight turns, exit the cab, and manually engage the slide. Automatic sliders offer seamless protection but add significant weight, complexity, and cost to your towing setup.
Understanding Your Truck’s Payload and Towing
The biggest myth in towing is that pulling capacity is the most important number. Many truck owners look at their vehicle’s maximum tow rating and assume they can safely tow any trailer under that limit. In reality, payload capacity is almost always the limiting factor when towing a fifth wheel.
Fifth wheels transfer 15% to 25% of their total loaded weight directly onto the truck bed as pin weight. A 12,000-pound trailer can easily generate a 2,400-pound pin weight. That weight, combined with the weight of the hitch itself, passengers, fuel, and gear, must not exceed the truck’s payload capacity.
| Truck Class | Average Payload Capacity | Safe Pin Weight Range | Recommended Fifth Wheel Weight |
|---|---|---|---|
| Half-Ton (1500) | 1,500 – 2,000 lbs | Under 1,000 lbs | Light/Ultra-Lite (Under 7,000 lbs) |
| Three-Quarter Ton (2500) | 2,500 – 3,500 lbs | 1,500 – 2,200 lbs | Mid-Profile (Under 12,000 lbs) |
| One-Ton (3500) | 4,000 – 7,000 lbs | 2,500 – 4,500 lbs | Full-Profile Luxury (Up to 20,000 lbs) |
To find your true capacity, locate the tire and loading information placard inside the driver’s door jamb. Subtract the actual weight of your fully loaded truck from your Gross Vehicle Weight Rating (GVWR) to see what pin weight you can safely carry. Overloaded trucks suffer from premature suspension wear, overheated brakes, and poor handling, making accurate weight calculations essential.
Step-by-Step Fifth Wheel Hitch Installation
Installing a fifth wheel hitch requires precision, basic mechanical skills, and the correct tools. Always perform this work on a flat, level surface with the truck’s parking brake fully engaged.
- Clear and Prep the Bed: Clean all debris from the truck bed. If you have an OEM puck system, remove the protective plastic caps and clean out any paint overspray from the factory mounting points.
- Position the Base: Lower the hitch base into the bed, aligning it with the rails or pucks. For puck systems, rotate the locking t-handles until they latch smoothly. For rail systems, insert the heavy-duty pins and secure them with cotter keys, ensuring the base is perfectly square.
- Adjust the Hitch Height: Mount the hitch head assembly to the base at the correct height. To determine this, measure from the ground to the bottom of your level trailer pin box, and match it to your truck bed height. You want at least 6 inches of clearance between the top of your truck bed rails and the underside of the trailer overhang.
- Torque the Bolts: Use a calibrated torque wrench to tighten all mounting bolts to the manufacturer’s exact specifications. Applying incorrect torque can lead to structural failure or excessive vibration during travel.
Before your first highway trip, perform a visual check and a low-speed “tug test” to ensure the jaws are fully engaged and locked around the kingpin.
Essential Maintenance Tips for Your New Hitch
The metal-on-metal contact between the trailer kingpin box and the hitch head generates extreme friction. Use a high-quality lube plate on the trailer kingpin to eliminate the need for messy grease on the flat surface of the hitch head. However, you must still apply heavy-duty lithium grease directly inside the locking jaws and pivot pins.
Road vibrations can slowly loosen even the toughest bolts over thousands of miles. Make it a habit to check the torque on all mounting bolts and rail pins before every major road trip. Inspect the hitch daily during travel for any signs of metal fatigue, cracked welds, or bent components.
Dirt and road grime act like sandpaper when mixed with grease inside your hitch mechanisms. Wipe down the moving parts periodically and reapply fresh lubricant. When the hitch is not in use, protect it from the elements with a heavy-duty vinyl cover, or remove it entirely and store it in a dry garage.
Choosing the right fifth wheel hitch is about matching your specific truck bed configuration, physical strength, and towing frequency to the perfect piece of hardware. By focusing on payload capacity and secure locking systems rather than just raw towing numbers, you protect your investment and ensure a stress-free travel experience. Take the time to install, maintain, and respect your connection point, and the open road will reward you with miles of smooth, reliable adventures.
