I was following a customer out of our parking lot one afternoon—he’d just bought a new 28-foot travel trailer and was heading home for the first time with it. As he pulled onto the road and merged into traffic, I watched him attempt a lane change by craning his neck around, leaning forward, and essentially guessing that the lane was clear. His factory side mirrors on the SUV showed him the front quarter of his trailer and nothing else. Everything behind the trailer’s midsection was a complete blind spot. He made it home safely, but he called me that evening and said, “Bill, I need towing mirrors. That drive was terrifying.”
It’s a scene I’ve witnessed countless times. New trailer owners get so focused on the hitch, the brake controller, the weight distribution system—all critical components—that they forget about the most basic safety requirement of all: being able to see what’s behind and beside them. Your factory vehicle mirrors were designed to show you the lanes alongside a vehicle that’s roughly six feet wide. When you add a trailer that’s eight feet wide or more extending twenty to thirty feet behind you, those factory mirrors become dangerously inadequate.
Towing mirrors extend your field of vision past the width and length of your trailer, restoring the rearward visibility that’s essential for safe lane changes, merging, backing up, and general road awareness. Many states legally require extended mirrors when towing wide loads, but even where they’re not legally mandated, they’re a safety necessity that no trailer owner should tow without. This roundup covers the best towing mirror options we carry at the RV Upgrade Store, from simple clip-on extensions to vehicle-specific snap-on systems.
Best for: Quick, affordable towing visibility for occasional towers and smaller trailers
The Camco Tow-N-See is the towing mirror I recommend to customers who want the simplest, most affordable way to see past their trailer. It’s a convex mirror that attaches to your existing side mirror and provides a wider field of view that extends your rearward visibility past the width of most travel trailers. The convex surface compresses the reflected image, which means you can see a wider area in a smaller mirror—the same principle used in the “objects may be closer than they appear” passenger-side mirrors on most vehicles.
The attachment mechanism is designed to work with most factory mirror shapes and sizes. It straps or clips onto your existing mirror housing without any permanent modification, drilling, or adhesive. Put it on when you’re towing, take it off when you’re not. For RV owners who tow occasionally—weekend trips, vacation hauls, seasonal moves—this removability is a genuine advantage. You don’t want permanently extended mirrors on your daily driver when there’s no trailer behind you.
The convex design does have a tradeoff: distance perception is distorted. Objects in a convex mirror appear farther away than they actually are, which can make judging the speed and distance of following traffic more difficult until you’ve calibrated your perception. This isn’t a dealbreaker—millions of drivers use convex mirrors daily—but it does require a brief adjustment period, especially when changing lanes on the highway.
At this price point, the Camco is essentially disposable insurance. Even if you plan to upgrade to a more sophisticated mirror system later, having a Tow-N-See in your glove compartment means you’re never caught without towing visibility. I keep a pair in the store’s checkout area because they’re the kind of impulse purchase that genuinely improves safety.
Pro Tip: Position the convex mirror so you can see the rear corner of your trailer and at least one full lane of traffic behind it. If you can only see the side of the trailer, the mirror is angled too far inward and won’t show you the traffic you need to see for lane changes.

Best for: A versatile, adjustable towing mirror that fits a wide range of factory mirror sizes
The CIPA clip-on mirror is a step up from the basic Camco in both adjustability and stability. It features adjustable arms that clamp onto your factory mirror housing and extend a flat towing mirror outward, past the width of your vehicle. The flat mirror surface provides true-distance reflection—unlike the convex Camco, objects appear at their actual distance, which makes judging traffic speed and spacing easier and more intuitive.
The adjustable design accommodates factory mirrors that are 7 to 10 inches tall, which covers the majority of trucks, SUVs, and crossovers used for trailer towing. The rubber strap attachment holds the mirror firmly against the factory housing without scratching or damaging the surface, and vibration during highway driving is well-controlled—the mirror stays in the position you set it without drifting or bouncing.
I recommend the CIPA clip-on to customers who tow regularly enough to want a better mirror than the basic convex options but who don’t want—or can’t find—a vehicle-specific snap-on mirror for their particular make and model. The universal fit means it works on virtually any vehicle, which is particularly valuable for RV owners who might tow with different vehicles depending on the situation.
The flat mirror surface is a meaningful advantage for highway driving. Accurate distance perception reduces the hesitation and uncertainty that many drivers feel when changing lanes while towing. You can see exactly how far away the car behind you is and how fast it’s approaching, which gives you the confidence to make lane changes decisively rather than waiting for an unreasonably large gap in traffic.
Pro Tip: When attaching clip-on mirrors, tighten the clamp firmly enough to prevent vibration but not so tight that you risk cracking the factory mirror housing. Plastic mirror housings can crack under excessive clamping pressure, especially in cold weather when the plastic is more brittle. Firm and secure, not gorilla-tight.
Buy the CIPA Clip-On Towing Mirror
Best for: Two mirror surfaces in one unit for both distance judgment and wide-angle blind spot coverage
The CIPA Dual-View solves the convex-vs-flat debate by giving you both mirror types in a single clip-on unit. The main mirror surface is flat for accurate distance perception, while a smaller integrated convex section provides wide-angle coverage for blind spot monitoring. It’s the best of both worlds in one attachment, and it’s the configuration I recommend most often for serious towing.
The dual-view design mirrors what you’d find on a factory truck mirror designed for towing—most heavy-duty pickup trucks from Ford, GM, and RAM come with factory mirrors that have both a flat main glass and a smaller convex spot mirror for exactly this reason. The CIPA Dual-View gives you the same functionality as an add-on for vehicles that didn’t come with built-in towing mirrors.
In practice, you use the flat surface for general rearward monitoring and lane-change decisions—it shows you what’s directly behind and beside the trailer at true distance. The convex section covers the wider area further back and to the side, catching vehicles that have moved into your blind spot or are approaching from several lanes over. Together, the two surfaces provide comprehensive rearward coverage that eliminates most of the blind spots created by a wide trailer.
The clip-on attachment is similar to the standard CIPA model—rubber-padded clamps that grip the factory mirror housing without damage. Adjustability is good across the range of common factory mirror sizes, and the dual-view surface holds its position well during highway driving. The unit is slightly larger than a single-surface mirror, which provides more viewing area but also adds a bit more wind resistance and visual bulk.
Pro Tip: Adjust the flat mirror to show the trailer’s rear corner and the lane behind it. Then adjust the convex section to show the area further out to the side. You want minimal overlap between the two surfaces—each should cover a different zone of rearward visibility for maximum coverage.

Best for: Chevy Silverado and GMC Sierra owners who want a custom-fit towing mirror with zero hassle installation
If you drive a 2019 or newer Chevy Silverado or GMC Sierra 1500, the K-Source Snap & Zap mirrors are the towing mirror upgrade I recommend before anything else. These are vehicle-specific mirrors designed to snap directly over your factory mirror housing with a precise, custom fit. No clamps, no straps, no adjustment arms—they literally snap on and snap off in seconds.
The custom fit is the key advantage. Because these mirrors are molded to match the exact contour of the Silverado/Sierra factory mirror housing, they sit flush and secure without any of the wobble, vibration, or shifting that universal clip-on mirrors can experience. The extended mirror surface provides the towing visibility you need, and the factory-matched profile looks like it belongs on the truck rather than looking like an aftermarket add-on.
The Snap & Zap design also means that the mirror extends further outboard than most clip-on alternatives, which provides better visibility past wide trailers. The extension is particularly valuable for owners who tow wider trailers—96-inch-wide travel trailers and toy haulers that exceed the truck’s own width by a significant margin. The further outboard the mirror extends, the better your view of the lanes beside and behind the trailer.
These are sold as a set—driver and passenger side—because you need both for proper towing visibility. I occasionally have customers ask if they can buy just one side, and my answer is always the same: blind spots don’t only exist on one side of the trailer. Both mirrors are equally important, and skipping one side to save a few dollars is a false economy when the safety of your lane changes depends on seeing what’s beside you.
One compatibility note: these mirrors are designed for Silverado/Sierra 1500 models without factory telescoping mirrors. If your truck already has power-extending towing mirrors from the factory, you don’t need these—your factory mirrors already provide the extended visibility. Verify your mirror type before ordering.
Pro Tip: After snapping the mirrors on, drive around the block and check for any vibration or movement before heading to the highway. If the mirror is buzzing or shifting, it may not be fully seated on the factory housing. Remove it, clean any dirt from the mating surfaces, and snap it back on firmly until you feel it click into position.

Best for: Aerodynamic, clamp-on towing mirror with a focus on minimizing wind noise and drag
The Milenco Aero3 takes a different design approach than traditional towing mirrors. Instead of a flat or simple convex surface mounted on an extending arm, the Aero3 uses an aerodynamically shaped housing that reduces wind noise and drag at highway speeds. If you’ve ever used a clip-on towing mirror that whistled, vibrated, or created noticeable drag at highway speeds, you’ll appreciate Milenco’s attention to aerodynamics.
The Aero3 is particularly popular with European RV owners—Milenco is a UK-based brand with a strong following in the caravan community—and it’s gained a loyal customer base in North America among RV owners who prioritize quiet, stable towing. The mirror surface is a convex design that provides wide-angle coverage, and the clamp attachment system fits a wide range of factory mirror shapes.
The blind spot designation refers to the mirror’s primary purpose: covering the area beside and slightly behind your trailer that falls outside your factory mirror’s field of view. It’s mounted lower and further outboard than your factory mirror, filling the gap that creates the dangerous blind spot when towing. The aerodynamic housing keeps the mirror stable and quiet even at sustained highway speeds, which is a genuine quality-of-life improvement on long towing days where constant mirror buzzing becomes genuinely fatiguing.
Build quality is excellent—the Milenco Aero3 feels like a premium product and is priced accordingly. The housing is UV-resistant and weather-resistant, designed to stay on the vehicle during inclement weather without degradation. The clamp mechanism is precise and adjustable, providing a firm grip without excessive pressure on the factory mirror housing.
For RV owners who spend significant time towing at highway speeds and want the quietest, most aerodynamic towing mirror available, the Milenco Aero3 delivers a noticeably different experience from traditional clip-on mirrors. The reduced wind noise alone is worth the upgrade for drivers who are sensitive to road noise or who tow with windows partially open.
Pro Tip: When mounting the Aero3, adjust the mirror angle before tightening the clamp fully. The aerodynamic housing makes angle adjustment slightly more difficult once the clamp is fully tightened, so get the viewing angle right while the clamp is finger-tight, then cinch it down for the road.

The decision between universal clip-on mirrors and vehicle-specific snap-on mirrors usually comes down to your vehicle and how often you tow. If a snap-on mirror exists for your specific make and model, it’s almost always the better choice—the fit is superior, the stability is better, and the appearance is more integrated. Vehicle-specific mirrors are designed for your mirror housing’s exact shape and size, which eliminates the guesswork of universal fitment.
If no vehicle-specific option exists for your vehicle, universal clip-on mirrors like the CIPA models are the way to go. They work on virtually any mirror housing, they’re adjustable to fine-tune the viewing angle, and they provide the extended visibility you need at a reasonable price. The dual-view model with both flat and convex surfaces gives you the most comprehensive coverage in a single unit.
Regardless of which type you choose, always install mirrors on both sides of the vehicle. Single-side mirror extensions leave a massive blind spot on the uncovered side, which is arguably worse than having no extensions at all because it creates a false sense of security. Both sides, every time.
Most states require that your vehicle’s mirrors provide a view of the highway for at least 200 feet to the rear. When you’re towing a trailer that’s wider than your vehicle, your factory mirrors may not meet this requirement. States including California, Florida, Texas, and many others have specific regulations about mirror extensions when towing wide loads. Penalties vary from warnings to fines, but the real consequence of inadequate mirrors isn’t the ticket—it’s the accident you could have avoided if you’d been able to see the vehicle in your blind spot.
Even in states without specific towing mirror laws, you can be cited for unsafe driving if your mirrors don’t provide adequate rearward visibility. And in the event of an accident where a lane change was involved, inadequate mirrors can be used to establish negligence. The cost of a pair of towing mirrors is trivial compared to the legal and financial exposure of a preventable accident caused by a blind spot you should have been able to see.
Towing mirrors are the most overlooked safety accessory in the RV towing world. Customers spend thousands on hitches, brake controllers, and weight distribution systems—all critical components—and then drive away without being able to see past their trailer. It’s like wearing a seatbelt but covering your windshield. The safety systems only work if you can see what’s happening around you.
Every product in this roundup provides the extended visibility that safe towing requires. From the simple, affordable Camco convex mirror to the precision-fit K-Source snap-ons and the aerodynamic Milenco Aero3, there’s a towing mirror solution for every vehicle, every budget, and every towing frequency. Pick the one that fits your truck, put it on every time you hitch up, and you’ll wonder how you ever towed without it.
