6 Weight Distributing Hitches For Large Travel Trailers That Tame Sway

You’re cruising down the highway, family in tow, and a semi-truck barrels past. Suddenly, your whole rig starts to wiggle, that unnerving side-to-side shimmy that makes your knuckles white and your stomach drop. This is trailer sway, and with a large travel trailer, it’s not just scary—it’s dangerous. The right hitch isn’t just a piece of metal connecting you to your adventure; it’s the tool that transforms a stressful tow into a confident, controlled journey.

Understanding Weight Distribution and Sway Control

Towing a heavy trailer is a game of physics. When you drop several hundred pounds of tongue weight onto your truck’s bumper, the rear end sags and the front end lifts. This lightens the load on your front steering axle, reducing traction, steering response, and braking effectiveness. A weight distributing hitch uses long steel arms, called spring bars, that act like levers to redistribute that weight, pushing some of it back to the trailer’s axles and, crucially, back onto your truck’s front axle.

Sway control is the other half of the equation. It’s the force that actively fights the trailer’s tendency to pivot side-to-side. Some hitches use simple friction, like a brake pad, to dampen the movement once it starts. More advanced systems use proactive designs, like cams or specialized geometry, to actively force the trailer to stay in line behind you. Think of it as the difference between tapping the brakes on a slippery corner versus having an advanced traction control system that prevents the slide from ever happening.

ProPride 3P for Complete Sway Elimination

For the RVer who wants the absolute pinnacle of sway control and is willing to invest in it, the ProPride 3P is in a class of its own. Imagine a windy day crossing the plains of Kansas, with crosswinds that would normally have you wrestling the steering wheel. With this hitch, the trailer and truck feel like a single, solid unit. It accomplishes this through a unique design that geometrically projects the trailer’s pivot point forward, right over your truck’s rear axle.

This isn’t sway damping; it’s sway elimination. The physics of the connection make it virtually impossible for the trailer to sway. The tradeoff is significant: this is the most expensive and heaviest hitch on the market. It also has a steeper learning curve for hitching up, especially if you’re not on perfectly level ground. But for full-timers or those towing massive trailers in challenging conditions, the peace of mind can be priceless.

Equal-i-zer 4-Point for Integrated Control

The Equal-i-zer is one of the most popular and trusted hitches you’ll see in any campground, and for good reason. It’s a workhorse that combines weight distribution and sway control into one simple, robust package. Its name comes from the four points of friction-based sway control built directly into the design: two where the spring bars connect to the hitch head, and two where they slide on L-brackets attached to the trailer frame.

This constant friction provides a stiff, secure connection that actively resists sway from the moment you start moving. It’s known for being a bit noisy—you’ll hear it groaning and popping in tight turns—but that noise is the sound of it doing its job. The integrated design means there are no extra sway control bars to install or remove. For a fantastic balance of proven performance, durability, and value, the Equal-i-zer is a top contender for weekend warriors and serious adventurers alike.

Blue Ox SwayPro for Quiet, User-Friendly Towing

If the thought of a noisy hitch makes you cringe, the Blue Ox SwayPro should be on your short list. This system is engineered for a quiet, smooth ride. It achieves sway control by using the tension of the spring bars themselves, which are held in place by rotating latches on the trailer frame. This design provides excellent control without the metal-on-metal grinding common in other friction-based systems.

One of the SwayPro’s most celebrated features is its ease of use. The rotating latches and included wrench give you leverage to connect the spring bars without the drama of lifting them onto high brackets. This makes the hook-up process faster and feel a bit safer. It’s an excellent choice for RVers who prioritize a quiet journey and a user-friendly design without sacrificing serious sway control performance.

Andersen No-Sway: A Unique, Lightweight System

The Andersen hitch throws the traditional rulebook out the window. Instead of heavy steel spring bars, it uses a patented ball and tapered friction cone system connected by heavy-duty chains and urethane springs. This innovative design provides exceptionally smooth and quiet weight distribution and sway control.

Its biggest advantage is weight. The Andersen is significantly lighter than most other hitches in its class, which can be a huge benefit if you’re pushing the payload limits of your tow vehicle. The hook-up process is also incredibly simple and the ride is often described as smoother than its competitors. While its unconventional look might give some traditionalists pause, its performance has earned it a fiercely loyal following, especially among those looking for a modern, lightweight solution.

Reese Strait-Line for Classic Dual-Cam Performance

Reese is a legacy name in the towing world, and their Strait-Line system with Dual Cam Sway Control is a time-tested classic. This isn’t just a friction system; it’s a proactive one. The "cams" on the trailer frame are designed to lock into the ends of the spring bars, actively working to pull the trailer back into a straight line behind the truck whenever it starts to sway.

This design provides powerful, self-centering action that gets stronger the more the trailer tries to sway. It’s a robust and highly effective system that has been proven over millions of miles. The initial setup can be a bit more involved to get the cams perfectly aligned, but once it’s dialed in, it’s a reliable and powerful towing partner for navigating gusty highways or emergency maneuvers.

CURT TruTrack: A Robust and Reliable Option

CURT’s TruTrack is another strong contender in the integrated hitch category, offering a design that combines the best of several worlds. It uses spring-loaded components, similar in concept to the cam systems, that actively engage to keep the trailer aligned. This provides proactive sway control that resists movement before it becomes a problem.

The TruTrack is built with heavy-duty, forged steel components, giving it a feeling of rock-solid reliability. The setup is straightforward, and once adjusted, it provides a stable and predictable towing experience. For those looking for a durable, high-performance hitch that competes directly with the established players, the TruTrack is a dependable choice that gets the job done without fuss.

Matching Hitch Capacity to Your Trailer’s Weight

This is the most critical part of your decision. Every hitch has two ratings: Gross Trailer Weight (GTW) and Tongue Weight (TW). Your trailer and all your gear must be below the GTW limit, and your actual tongue weight must fall within the hitch’s specified TW range. Tongue weight should be 10-15% of your trailer’s total loaded weight.

Don’t guess. The sticker on your trailer shows its empty weight, not its weight when loaded with water, propane, food, and gear. The only way to know your true weights is to take your fully loaded rig to a CAT scale. A hitch that is underrated for your tongue weight is dangerously overloaded. Conversely, a hitch that is massively overrated won’t flex properly and will create a harsh, jarring ride. Matching the hitch’s capacity to your actual, loaded trailer weight is non-negotiable for a safe trip.

Choosing the right hitch can feel overwhelming, but it’s one of the most important gear decisions you’ll make. It’s the foundation of a safe and low-stress towing experience. Don’t get lost in the specs; focus on what matters—a system that matches your trailer’s weight and gives you the confidence to handle whatever the road throws at you. The real goal isn’t to own the perfect piece of steel, but to get your rig safely to the next beautiful campsite.
