A quiet, well-indicated hitch designed to eliminate guesswork at the moment of coupling.

You get clear confirmation that your trailer is safely attached with the CURT Q20, thanks to a built-in 3-position indicator that shows coupled, uncoupled, or ready to tow. It carries the same 20,000 lb gross trailer weight and 5,000 lb vertical load rating as the B&W Companion RVK3500, but the visual check removes the nagging doubt about whether the jaws truly engaged. This is the pick for daily hookups where confidence matters most.

Underneath, a spherical axial bearing lets the head tilt in any direction needed, which owners say reduces the struggle when the truck and trailer are parked at different angles. The single short-throw handle is lockable for security, and owners mention the ride stays quiet on the highway. It runs at 140 pounds, so this is a substantial unit, but the Q-series design is explicitly built for the quietest possible towing, and owners confirm that smoothness on long hauls.

One caveat: it is not compatible with articulating or turret-style pin boxes like Rota-Flex and Sidewinder, so check your pin box before committing. It fits standard industry base rails, including CURT rails #16104 and #16204, which are sold separately. For those who want failsafe design cues and a quieter cabin, this is a strong mid-premium choice.

A purpose-built steel fortress for Andersen Ultimate couplers that shrugs off brute force attacks.

Something is different when a security product lists its specs as “Bolt Cutter Proof” and “Crowbar Proof.” This Ft. Knox lock is machined from heavy-duty industrial-grade welded steel specifically to fit the Andersen Ultimate 5th wheel conversion coupler, creating a precise, secure fit that leaves no exposed metal for tools to grab. Its non-universal, tight fit is what makes it so hard to defeat.

The package includes a Trimax Puck Lock, delivering what Ft. Knox calls a full-enclosure security solution. Buyers call it “a tank” and praise how easily it slides over the Anderson coupler. It weighs in at 18 pounds, which tells you the steel is genuinely thick. The catch, noted honestly by owners, is that you have to disconnect your safety chains from the eyebolts to slide the lock over them, so plan your hookup routine accordingly.

Made in the USA by a family-run business, this lock suits contractors, haulers, and RV owners who leave a trailer parked and want serious theft deterrence. Owners praise the build quality most, with durability close behind. If you run a gooseneck or a standard rail hitch, this is not your lock — but for Andersen couplers, nothing else in this guide matches its focused protection.

Clears the truck bed of a bulky hitch by dropping your 5th wheel onto a gooseneck ball.

This adapter solves a specific problem: you want the towing stability of a 5th wheel but you do not want a large hitch consuming your truck bed. The Eaz-Lift bolts onto your trailer’s king pin box and its locking coupler attaches to any standard 2-5/16 inch gooseneck ball. With a 30,000 lb tow rating and a 7,500 lb vertical load capacity, it is rated well above most consumer rigs.

Plan for a real installation project here. Customers note the bolt-on process itself is fast — one owner completed it in about a minute on a dealer lift — but the real work is drilling the holes in your trailer frame to mount it, which requires a hole saw and patience. The spring-loaded coupler allows a full range of motion, and once the trailer settles onto the ball, it self-locks and you secure the pin.

The payoff is a completely clear truck bed, which is why contractors and weekend haulers love it. The overall height sits at 15 inches, and owners running 40-foot trailers report smooth 500-mile pulls without issues. The one consistent warning from owners is to use proper bolts (some report mismatched hardware in the kit) and to consider corner bolts for extra theft resistance. This is a mid-to-upper-tier pick for a very specific towing lifestyle.

A conical cast-steel shield that deflects a thief tractor’s 5th wheel plate on contact.

WAR-LOK designed the TKP-10 for the specific scenario of a dropped, untethered trailer sitting in a lot. The conical shape of this cast steel lock deflects the fifth wheel plate of a would-be thief tractor, making it physically difficult to line up and connect. It is built to protect expensive cargo in a dropped trailer from exactly that kind of theft.

At 5.044 lbs with dimensions of 12 x 9 x 2.875 inches, it is a substantial piece of metal. The Rotating Disk Lock Technology makes it nearly impossible to pick, and lost keys can be replaced if you register them with the manufacturer. The built-in handle makes it easy to carry and position, and the bright metallic finish acts as a visible deterrent — something reviewers point out is half the battle.

Reviews consistently call it solid, durable, and easy to install, with the all-steel (not aluminum) construction standing out. The honest caveat is that the locking mechanism itself earns mixed feedback; most owners have no trouble, but a few note the key mechanism is not the smoothest. One owner fitting it to a Momentum toy hauler appreciated that it worked without removing the lube plate. If you have an autoslider hitch, you may need to remove the second plate for a snug fit. It is a reliable, heavy-duty deterrent rather than an absolute guarantee.

A family-built steel lock that makes hooking up to your trailer physically impossible for a thief.

The VULCAN lock answers the most common security question — how do I stop someone from driving off with my trailer — with a simple mechanical block. The solid steel cuff covers the entire king pin, which means a 5th wheel cannot physically mate with it while the lock is engaged. At 2.42 pounds, it is lively and easy to handle, yet the chromed steel construction is built to resist tampering.

You get serious theft deterrence because the forged locking pin cannot be disengaged without the key, and each set ships with a slide bolt lock and two keys. Shoppers say it is very easy to put on and take off, fits any truck and trailer combination, and represents real value next to truck-stop pricing. As one owner put it plainly: “This is made out of steel and made to last.” The high-gloss finish resists the elements, though a handful of owners have noted rust developing over time in harsh conditions — worth a wipe-down now and then.

VULCAN is a family-owned Detroit business operating since 1959, now in its fourth generation, which gives the purchase a reassuring provenance. While the WAR-LOK above offers a conical deflector for dropped trailers, this lock is the simpler, more affordable universal deterrent for standard king pins. If you want solid theft protection without the premium price tag, this is the one to grab.

The front-end stabilizer that kills that annoying shake when you walk through the living room.

If you have ever been in the front of a 5th wheel while someone walks to the bathroom, you know the wobble problem. This tripod stabilizer jacks under the king pin area to significantly reduce that side-to-side motion. It is rated for a 5,000 lb load, which comfortably supports the front of most consumer rigs. One owner with a 37-foot toy hauler confirmed it handles the weight perfectly.

The standout feature is hybrid operation: you can raise it manually with the included handle, or attach the included drill adapter and crank it down in seconds. That drill compatibility is what buyers rave about for cutting down setup time. The adjustable height spans 35 to 56.7 inches, with a hitch cup featuring an adjustable hole to fit different king pin configurations. Buyers report it even withstood winds over 50 mph when properly set.

from the start it needs no assembly — just secure the chain and it is ready. The sturdiness and build quality are the most-praised aspects, and the alloy steel frame with powder-coating finish is built for repeated use. The honest notes: one owner’s foot detached before first use and needed welding, and the included lock is not the best quality. It is a sturdy, effective comfort upgrade, best for anyone tired of a shaky front end at the campsite.

A tailored weather shield that keeps your expensive hitch free of rust, grease, and sun damage.

Your 5th wheel hitch is a precision piece of steel that spends most of its life exposed to the elements. This cover from Classic Accessories fits 15K hitches and works to protect against dirt, grease, rust, and harmful UV rays — the three things that quietly degrade an expensive hitch over years of storage. It attaches with an elastic cord and hook-and-loop straps, so it goes on in minutes.

The material is a vinyl exterior with a felt interior, and buyers consistently note the quality stitching and hardware. Owners mention it fits larger units like the Reese 20K “perfectly” and even covers the base of a Ford OEM Companion 20k. One long-haul user in Arizona’s punishing sun confirms it protects from heat and contains grease, holding up at highway speeds. The recurring praise centers on functionality and protection, with owners reporting years of service — one noted the top was still fine after five years.

The honest trade-offs: some owners find the velcro straps poorly designed, with the hook-and-loop on the same side causing the cover to ride up on the legs, and a bottom section can deteriorate after a year or two in harsh sun. Compared to a name-brand cover, this delivers most of the protection at a fraction of the commitment. It comes with a three-year limited warranty and weighs 2.2 pounds, making it easy to stow when not in use. If you leave your hitch in the truck bed, this is the cheapest insurance you can buy for it.

The backup connection that turns a potential hitch failure into a controlled stop instead of a crash.

Safety chains are the piece of gear you hope you never need but absolutely should not skip. These Andersen chains are rated at 18,000 lb per chain — that is the critical safety figure — and they act as a backup connection between your 5th wheel trailer and tow vehicle. If the hitch disconnects for any reason, these Grade 70 chains are what keep the trailer attached and under control. Buyers describe a real-world save where the chains held a 5th wheel after a hitch failure, allowing a safe stop.

The kit works with both the rail mount and gooseneck versions of the Andersen Ultimate 5th Wheel Connection, so you get the right solution regardless of your setup. It comes complete with 2 safety chains, 3 eyebolts, 2 shackles, and 2 extended bolts — everything you need. Installation earns consistent praise for being straightforward with clear instructions, and the extended bolts and threaded eyelets replace the kingpin coupler bolts that ship with the Ultimate Connection.

At 9.5 pounds, the alloy steel kit feels substantial. Owners are quick to note it beats imported knockoffs that often lack instructions and proper fit. The one pointed critique is that the included shackles are the weak link in the system; a detail-oriented owner swapped them for stronger quick links for extra margin. This is a mid-price essential for any Andersen Ultimate user who values redundant safety on every haul.
