6 Best RV Electrical Outlet Covers For Outdoor Use Nomads Swear By

You’ve just pulled into a rainy campsite, and the first thing you need is power. But your RV’s exterior outlet is guarded by a cheap, flimsy plastic flap that offers zero real protection. This small, overlooked detail can lead to big problems, which is why a proper weatherproof outlet cover isn’t a luxury—it’s an essential upgrade for any serious nomad.

Why Your RV Needs a Weatherproof Outlet Cover

Your rig lives outside, exposed to everything nature throws at it. Sun, rain, snow, and dust are constantly trying to get inside, and your electrical outlets are a prime point of entry. The standard-issue covers that come from the factory are often brittle, UV-damaged plastic flaps that barely qualify as "weather-resistant," let alone weatherproof.

When that flimsy cover fails, water gets in. This leads to corroded terminals, tripped GFCI breakers, and in the worst cases, dangerous short circuits. A proper weatherproof cover, especially an "in-use" model that protects the plug while it’s connected, creates a sealed environment. This is critical for anything you leave plugged in for extended periods, like festive string lights, an outdoor kitchen appliance, or a battery tender.

Think of it as one of the cheapest, highest-impact insurance policies you can buy for your RV’s electrical system. For less than the cost of a tank of gas, you can prevent hundreds or even thousands of dollars in damage and diagnostic headaches. It’s a small investment that pays for itself the first time you’re caught in an unexpected downpour without having to scramble to unplug everything.

TayMac MM410C: The In-Use Weatherproof Cover

When you see a deep, bubble-style cover on an RV, it’s likely a TayMac or something very similar. Its defining feature is that deep profile, which allows you to keep bulky plugs and adapters connected while the cover remains fully closed and sealed against the elements. This is the gold standard for "in-use" protection.

Made from a high-impact polycarbonate, the TayMac is built to withstand bumps, scrapes, and the relentless UV exposure of life on the road. Most kits come with multiple adapter plates and inserts, allowing you to configure them for standard duplex, decorator-style GFCI, or single round outlets. This versatility makes it a fantastic choice for retrofitting onto almost any rig, whether the outlet is mounted vertically or horizontally.

This cover is for people who truly live out of their RVs. Imagine you’re running a small electric heater to keep your water bay from freezing on a cold night, or you’ve set up a slow cooker outside to keep the heat out of your rig. The TayMac is for nomads who actively use their outdoor power, not just for occasional access. It provides peace of mind that your connection is safe, no matter what the weather does.

Leviton 5981-U: A Durable, Low-Profile Option

Not everyone needs a bulky "in-use" bubble. The Leviton 5981-U represents the other end of the spectrum: a sleek, durable, and low-profile flip-up cover. When closed, it sits nearly flush against the side of your RV, reducing the chances it will get snagged on a tree branch or clipped in a tight parking spot.

Leviton is a heavyweight name in the electrical world, and their quality shows. These covers are typically made from a rugged thermoplastic with a stainless steel hinge pin and a heavy-duty spring mechanism that snaps the lid shut with authority. The full perimeter gasket creates a fantastic seal when closed, keeping dust and driving rain out with ease.

The trade-off is clear: its low-profile strength is also its main limitation. It provides excellent protection for the outlet itself, but it’s not designed to be used in wet conditions. This makes it a perfect, robust replacement for a broken factory cover on an outlet you only use temporarily—plugging in a shop vac, charging a power tool, or briefly running a cord. It’s a simple, reliable upgrade for outlets that need to be protected, not constantly in use.

Camco 55323: The RV-Specific Power Outlet Box

Sometimes, the problem isn’t just the cover—it’s the whole assembly. Years of sun and vibration can leave the original plastic outlet box cracked and crumbling. This is where a purpose-built RV solution like the Camco 55323 Power Outlet Box shines. It’s not just a cover; it’s a complete replacement unit.

Camco is a brand every RVer knows, and they design products specifically for the unique demands of mobile life. This kit typically includes a new outdoor-rated outlet, the housing box, and a hinged, weatherproof cover all in one package. The installation is straightforward, designed to replace the common-sized units found on thousands of trailers and motorhomes.

This is your go-to option when a simple cover swap won’t cut it. If the mounting screws on your old box have stripped out or the plastic housing itself is failing, retrofitting a residential cover can be a frustrating exercise. The Camco unit is less of an upgrade and more of a direct, reliable restoration to get your rig safely back to factory spec.

Hubbell-Bell 5320-0: Heavy-Duty Metal Security

If you’re looking for the most rugged, bombproof cover you can bolt to the side of your rig, look no further than an industrial-grade metal cover from a brand like Hubbell-Bell. Made from die-cast aluminum or zinc, these covers are designed to survive on construction sites and in factories. For an RVer who frequents rough backcountry roads or simply wants maximum durability, this is the answer.

The metal construction isn’t just about impact resistance; it’s also about security. Many of these models, like the 5320-0, feature an integrated, lockable hasp. This is an invaluable feature if you store your RV or worry about power theft in a campground. It also provides an excellent layer of childproofing, keeping curious hands away from live electricity.

Of course, there are downsides. Metal is heavier, more expensive, and can be more involved to install correctly, sometimes requiring a specific type of junction box. It’s definitely overkill for a weekend warrior, but for the full-timer demanding absolute maximum durability and security, it’s the right call.

Sigma Electric 14250WH: Versatile & Paintable

For the RVer who values both function and form, the Sigma Electric 14250WH is a fantastic choice. Like the Hubbell-Bell, it’s a durable, die-cast metal cover that offers superior protection compared to plastic. But its key feature is its finish—a powder coat that’s designed to be easily paintable.

This is a huge deal for anyone with a custom-painted rig or who simply can’t stand the look of a mismatched white or grey box on their beautiful RV. A light scuff with sandpaper and a few coats of color-matched automotive paint allow this cover to blend in seamlessly. These kits are also known for their versatility, often including multiple inserts to accommodate different outlet styles within the same housing.

The Sigma strikes a perfect balance. It provides the toughness of an industrial metal cover with the aesthetic flexibility that many RV owners crave. It’s for the nomad who is willing to put in a little extra effort to get a clean, professional look without compromising on protection.

Red Dot S120E: Single-Gang Flip-Lid Simplicity

Sometimes, the best solution is the simplest one. The Red Dot S120E is the definition of a no-frills, reliable workhorse. It’s a single-gang, spring-loaded flip-lid cover that does one job and does it exceptionally well: it keeps the elements out of your outlet when it’s not in use.

There are no complex bubble enclosures or multi-piece inserts here. It’s a solid metal lid, a robust hinge, a strong spring, and a thick gasket. You lift it, plug in your cord, and when you unplug, it snaps shut with a satisfying thud. That spring-loaded action is a key feature, ensuring the cover never accidentally flops open while you’re bouncing down a forest service road.

This is the perfect upgrade for the minimalist. It’s for the RVer who wants something significantly tougher than the factory plastic flap but doesn’t need an in-use cover or a lock. Think of it as the professional-grade version of the basic cover, built for a lifetime of use.

Key Features: Gaskets, Locks, and Cord Ports

When you’re comparing covers, the details matter. The first thing to inspect is the gasket. This simple foam or rubber seal is the single most important component for keeping water out. Look for a thick, pliable gasket that fully encircles the outlet opening and creates firm, even pressure when the cover is closed.

Next, consider a lockable tab. Even if you don’t think you need it now, a small hasp that can accept a padlock is a great feature to have. It’s perfect for securing your power source in a storage yard, preventing neighbors from "borrowing" a little electricity, and adding a crucial layer of safety if you travel with small children.

Finally, if you’re choosing an "in-use" bubble cover, pay close attention to the cord ports. These are the notches at the bottom that allow the cord to exit while the cover is shut. Ensure they are large enough to accommodate the heavy-gauge cords you use and, ideally, have some form of foam or rubber baffling to help keep bugs and blowing rain from getting in around the wire.

Your RV’s exterior outlet is a direct gateway to its sensitive electrical system. Protecting it with a proper cover isn’t just about convenience; it’s about safety and preventing costly, frustrating repairs down the road. Choose the right one for how you travel, and you’ll have one less thing to worry about when the weather inevitably turns against you.
