5 Best Waterproof Beach Gear Storage Solutions For RVs Nomads Swear By
Keep sand out of your rig with nomad-tested gear.
There’s a moment every RVing beach lover knows. You’re back from a perfect day on the water, sun-kissed and tired, and you’re faced with a pile of wet, sandy gear. The choice is stark: bring it inside and deal with the gritty, damp mess for days, or leave it outside to bake in the sun and attract critters. This single, recurring problem can sour the entire coastal experience, turning your clean, cozy rig into a damp sandbox on wheels.
The truth is, your RV is not designed to handle sand and saltwater. Sand grinds away at flooring, clogs plumbing, and works its way into every mechanical system. Persistent moisture from wet towels and wetsuits is even more sinister, creating the perfect environment for mold, mildew, and the dreaded delamination that can destroy an RV’s structure from the inside out. Protecting your investment and your sanity requires a dedicated strategy.
This isn’t just about buying a box; it’s about creating a system that separates your wet, sandy adventure life from your clean, dry living space. The best solutions are external, weatherproof, and designed for the specific gear you carry. For nomads who live and breathe the coastal lifestyle, getting this system right is non-negotiable. It’s the key to making beach life sustainable, clean, and stress-free.

Why Your RV Needs Waterproof Beach Storage
The single greatest threat to your RV’s interior is sand. It’s an invasive force that defies brooms and vacuums, embedding itself in upholstery, scratching sensitive surfaces, and finding its way into your bed. More than just an annoyance, this grit accelerates wear and tear on everything it touches, from your flooring to the delicate tracks on your slide-outs. A proper external storage solution acts as a firewall, stopping the sand at the door.
Even more damaging than sand is moisture. A single wet towel or wetsuit left inside an RV can raise the humidity to levels that promote mold and mildew growth within 24-48 hours. This not only creates a health hazard but can lead to rot and delamination—a catastrophic failure of the laminated wall structure that is incredibly expensive, if not impossible, to repair. Waterproof storage contains this moisture outside, where it belongs.
Ultimately, dedicated beach gear storage is about creating a seamless workflow. It means you can pack up from the beach, stow your gear securely and externally, and step into a clean, dry rig without a second thought. This isn’t a luxury; it’s a fundamental component of efficient small-space living that protects your home, saves you hours of cleaning, and lets you focus on the adventure itself.
1. Thule Motion XT XL: Maximize Your Roof Space
Enhance your adventures with the Thule Motion 3 rooftop box. Its aerodynamic design reduces drag for better fuel efficiency, while the PowerClick system ensures quick, secure mounting with an integrated torque indicator. The SlideLock system offers easy opening and automatic locking for peace of mind.
Rooftop cargo boxes are the classic solution for a reason: they get bulky gear completely out of your living space. The Thule Motion XT XL is a standout in this category, offering a massive amount of storage in an aerodynamic, weatherproof shell. This is the perfect home for lightweight but awkward items like beach chairs, umbrellas, pop-up canopies, and foam bodyboards.
The primary benefit is total separation. Once the lid is closed, your sandy, wet gear is sealed off from the elements and, more importantly, from your rig’s interior. These boxes are designed to withstand highway speeds in a rainstorm, so a little salty sea spray is no challenge. The dual-side opening feature is also a massive practical advantage, allowing you to access your gear from whichever side of the RV is more convenient at your campsite.
The main tradeoff is height. You must be constantly aware of your new, taller clearance, as a low-hanging branch or bridge can cause serious damage. You’ll also need a robust, properly installed roof rack, and lifting heavier items can be physically demanding. For this reason, rooftop boxes are best suited for gear that you load and unload once per trip, not items you need to access constantly.
2. StowAway2 Max: Your Hitch-Mounted Gear Locker
Expand your vehicle's cargo space with the StowAway Max. This hitch-mounted storage box features a SwingAway frame for easy access and holds up to 16 cubic feet of gear, with included locking latch and tail lights.
If lifting gear onto the roof isn’t for you, a hitch-mounted cargo box is the answer. The StowAway2 Max is essentially a heavy-duty, waterproof trunk that attaches to your receiver hitch. It’s built to handle heavier, messier items like portable grills, fishing tackle, or a bin full of sandy toys, all at a comfortable, back-friendly height.
The swing-away frame is its killer feature. Unlike fixed boxes that block access to your rear doors or storage bays, the StowAway2 pivots completely out of the way, giving you unfettered access to the back of your rig. This is a game-changer for vans, Class Cs, and travel trailers where rear access is critical. The hard-shell construction is also lockable and completely waterproof, providing secure, dry storage.
Of course, this solution adds to your overall length, which can impact parking and maneuverability, especially when backing into tight spots. You must also account for your hitch’s tongue weight capacity, factoring in the weight of the carrier and its contents. This option is an excellent primary storage locker, but it does occupy your receiver hitch, making it a choice between the cargo box and a bike rack.
3. YETI Panga Duffel: Your Grab-and-Go Solution
Keep gear bone-dry with the YETI Panga 75 submersible duffel, featuring an airtight Hydrolok zipper and a puncture-resistant Thickskin shell. Its comfortable Dryhaul straps and durable Metallock hardware make it ideal for any adventure.
Sometimes the best solution isn’t mounted to your rig at all. The YETI Panga Duffel is a fully submersible, 100% waterproof bag that serves as a mobile quarantine zone for your wettest gear. Think of it as the first line of defense, containing the mess right at the source before it ever has a chance to touch your RV.
Its real-world application is simple and brilliant. At the end of your beach day, you stuff dripping wetsuits, salty rash guards, and soaked towels directly into the Panga. The airtight zipper seals the moisture and odor inside, creating a self-contained package you can toss in your external shower, a storage bay, or the back of your truck without a single drop leaking out. It effectively bridges the gap between the beach and your long-term storage.
The Panga is not meant to hold your beach chairs or umbrella; it’s a specialized tool for managing wet, pliable goods. The high price point is a definite consideration, but its rugged construction means it will likely outlast any other bag you own. For those who frequently deal with sopping wet gear like wetsuits or dive equipment, its effectiveness in preventing interior moisture makes it a worthwhile investment in your RV’s longevity.
4. MORryde Tray: Unlock Your Underbelly Storage
Easily access your RV batteries with this sliding tray. Features a 100% extension on ball bearing slides and a durable black powder coat finish.
Your RV’s pass-through storage bay is a massive asset, but it often becomes a deep, disorganized cavern. The MORryde Tray is an aftermarket slide-out system that completely revolutionizes this space. While the tray itself isn’t waterproof, it is the key that unlocks an incredibly effective waterproof storage system.
The concept is to use the slide-out tray to provide easy access to large, sealed plastic totes—like the ubiquitous 27-gallon black bins with yellow lids. You can designate specific bins for specific beach gear: one for snorkels and fins, another for beach toys, and a third for rolled-up beach mats. When you need something, you simply slide the tray out, open the correct bin, and slide it back in, all without crawling into the storage bay.
Organize and protect your belongings with this durable, stackable 27-gallon storage container. Featuring a snap-tight lid, ergonomic handles, and weather-resistant design, it's ideal for home, garage, or commercial use.
This system keeps all the sand and residual moisture contained within the plastic bins, protecting the underbelly of your rig. It’s an elegant solution that maximizes a huge, pre-existing space that is often underutilized. The initial installation requires some work, but the organizational and practical payoff is immense, turning a black hole of storage into a highly efficient gear garage.
5. Earth Pak Dry Bag: Your Budget-Friendly Choice
Keep your gear dry on any adventure with the Earth Pak Waterproof Dry Bag. Featuring a roll-top closure and included IPX8 waterproof phone case, it's lightweight and easy to pack.
You don’t always need a high-tech or permanently installed solution. The classic roll-top dry bag, like the popular and affordable ones from Earth Pak, is one of the most versatile tools in a nomad’s arsenal. It’s the simplest, most adaptable form of waterproof storage you can have.
Their strength is their flexibility. A 10L bag is perfect for protecting your phone, keys, and a book from sand and spray while you’re on the beach. A larger 40L bag can easily swallow a couple of wet towels and swimsuits for the trip back to the rig. You can hang them from a ladder to dry, tuck them into any small exterior compartment, or use them to organize gear within a larger, non-waterproof storage box.
A dry bag won’t hold a beach chair, but that’s not its purpose. It’s the perfect micro-solution for managing the small, wet items that cause the most trouble. Having a few of these in different sizes on board is a low-cost, high-impact strategy. It gives you the power to isolate wet items on the fly, making it an essential component of any comprehensive beach storage plan.
How to Choose Your Perfect Storage Solution
The right answer isn’t about finding the single "best" product, but about building the best system for your travel style. A solo van-lifer with a surfboard has vastly different needs than a family of four in a fifth wheel with an arsenal of beach toys. Start by analyzing your gear and your rig, not by looking at product catalogs.
To find your ideal setup, ask yourself these four questions:
- What are you storing? Is it bulky but light (chairs, umbrellas), or dense and heavy (dive weights, cast-iron grill)? The answer dictates whether you should look at a roof or hitch solution.
- What is your rig’s capacity? A small Class B can’t handle a massive hitch box, while a large Class A has a sprawling roof and huge underbelly bays. Work with the space you have.
- How often do you need access? Gear used daily should be easily accessible, like in a hitch box or a portable duffel. Items used once a trip can go on the roof.
- What is your budget? You can build a highly effective system with a few dry bags and plastic totes for under $100, or you can invest over a thousand dollars in a premium hard-shell carrier.
Most experienced nomads don’t rely on a single solution. They combine them. They might use a Thule box for the chairs and umbrella, a YETI Panga for the wetsuits, and a MORryde tray with bins for all the smaller toys and gear. The goal is to create a layered system where every piece of beach equipment has a designated, waterproof home outside your living quarters.
Keep Your Gear Dry and Your Rig Sand-Free
At the end of the day, sand and water are the persistent enemies of your mobile home. Every grain of sand you keep outside, and every drop of moisture you prevent from seeping into your walls, is a direct contribution to the longevity and value of your RV. This isn’t just about cleanliness; it’s about asset protection.
Creating a deliberate, externalized storage system is a core principle of successful RV living. It draws a clear line between your "garage" and your "living room," which is essential when both occupy the same small footprint. This separation reduces stress, minimizes cleaning time, and eliminates the risk of costly, moisture-related damage.
By investing in the right storage solution—or combination of solutions—for your needs, you are buying back time and peace of mind. You get to spend more of your energy enjoying the sunset and less of it sweeping up sand or worrying about that damp smell. A smart storage strategy is what transforms the dream of coastal RVing into a sustainable, enjoyable reality.
Ultimately, the best waterproof beach gear storage is the one that seamlessly integrates with your RV and your lifestyle. Whether it’s a rooftop box, a hitch-mounted locker, or a simple collection of dry bags, the right system frees you from the constant battle against sand and moisture. Choose wisely, and you’ll ensure your RV remains a sanctuary, not a sandbox, no matter how many amazing days you spend by the sea.
