MirroGuard Extended Towing Mirrors, Universal Clip-On Side Mirror Extensions for Pickups, RVs, and Trailers, Tow Mirrors with Extenders (Model MG91) (Black) Review (2026)

Who These Tow Mirrors Are For

These mirrors are built for drivers who tow a trailer, fifth wheel or RV wide enough that a factory side mirror no longer shows the full width of the load. Because the MG91 clips onto an existing mirror rather than replacing it, it suits owners who only need the extra sightline while towing and want to remove the extensions the rest of the time, rather than committing to a permanent tow mirror replacement. Named brand and model status also matters here. MirroGuard sells a dedicated MG91 and MG94 repair kit, which makes it easier to source replacement straps or hardware later than with a generic, unbranded clip-on mirror.

Mounting, Rotation and Materials Explained

The mirror heads rotate a full 180 degrees, letting a driver angle the extended view to match the width of whatever they are towing that trip, from a narrow utility trailer to a wide fifth wheel. Installation relies on adjustable straps and secure hooks that clamp around the factory mirror housing, a design meant to work across a range of factory mirror shapes without needing a vehicle specific bracket. The rubber components are built for varied climate conditions, and a non-slip design at the clamp points is meant to keep the extension from rotating or sliding once it is tightened down. MirroGuard sells the MG91 in black, military green and fluorescent green finishes, letting a buyer match or contrast with their tow vehicle.

Installing and Living With Them on the Road

Fitting the mirrors is a clip-on job, wrapping the straps around the factory mirror and tightening the hooks until the extension sits firmly against the housing, a process meant to take a few minutes without tools. Because the mirrors are held on by tension rather than a permanent bracket, they can be removed after a tow and reinstalled on a different vehicle, which suits drivers who tow occasionally rather than daily. On longer tows, vibration from the road can gradually loosen strap tension, so checking that the mirrors are still firmly seated during fuel or rest stops is worth doing, especially before highway driving with a wide load.

Trade-offs and How It Compares

The main trade-off with any universal clip-on mirror is fit. Because the MG91 is designed to work across a range of factory mirror shapes rather than one specific vehicle, it may not seat as securely on an unusually shaped or oversized factory mirror as a mirror extension built for that exact model. MirroGuard addresses part of this with its available MG91 and MG94 replacement parts kit, so straps or clamps that wear out from repeated towing do not require buying an entirely new set of mirrors. Drivers who tow the same wide trailer constantly, rather than occasionally, may eventually prefer a permanent tow mirror replacement over a clip-on extension that needs periodic re-tightening. Either way, checking the fit against your specific tow vehicle's mirror shape before a long trip is worth the few minutes it takes.

Verdict and Who Should Pick a Different Setup

These mirrors suit drivers who tow occasionally or with different trailers over time and want an extended sightline they can install and remove as needed, without a permanent mirror swap. Owners who tow the same wide load on every trip may find a dedicated, permanently mounted tow mirror a more secure long-term option. For most part-time towing situations, the MG91's rotating heads, multiple color options and available replacement parts make it a practical, named brand choice in the crowded clip-on mirror category. Checking strap tension before every tow is a small habit that keeps the extended view reliable over time.
