6 Best External Storage Bags For Bulky Gear Items For Rvs

Stowing bulky gear in an RV often feels like playing a high-stakes game of Tetris where every square inch is accounted for. External storage bags offer a vital reprieve, moving cumbersome items like camping chairs, oversized blankets, or trekking gear outside the living quarters. Selecting the right carrier requires balancing weight distribution, weather resistance, and accessibility to ensure the rig remains nimble on the road.

Rightline Range 3: Best Hitch-Mounted Bag

The Rightline Range 3 shines for those who prioritize accessibility over aerodynamics. By utilizing a hitch-mounted rack rather than the roof, this bag keeps your heavy gear within reach, sparing your back from lifting items overhead. It is a perfect match for solo travelers or families who frequently need to access their gear at roadside stops without deploying a ladder.

This bag is built with a proprietary, heat-resistant bottom, which is a critical detail for anyone mounting gear near an exhaust pipe. Because it sits behind the RV, it remains shielded from the high-speed wind resistance that plagues rooftop carriers. If the primary goal is minimizing height clearance issues while keeping the center of gravity low, the Range 3 is the undisputed leader.

Thule Interstate: Best Premium Rooftop Bag

When durability and long-haul performance are the top priorities, the Thule Interstate stands in a class of its own. This carrier uses heavy-duty, water-resistant materials and welded seams that withstand sustained highway speeds and intense UV exposure. It is designed for the traveler who views an external bag not as a temporary solution, but as a permanent extension of the RV’s storage capacity.

The Interstate includes high-quality compression straps that prevent the “flapping” noise commonly associated with cheaper rooftop bags. While the price point is higher, the investment is justified for those moving through diverse climates where the gear must stay bone-dry and secure. If your budget allows, choose this bag to avoid the frustration of replacing inferior products after a single season.

Rightline Saddlebag: Most Innovative Option

The Rightline Saddlebag effectively turns the back of a vehicle or the rear wall of an RV into usable storage real estate. It clips directly onto the rear door or an existing rack system, utilizing vertical space that typically goes ignored. This design is exceptionally clever for small camper vans or rigs where mounting a hitch or climbing to the roof is physically difficult.

This bag excels at storing “dirty” gear—wet raincoats, muddy boots, or garden tools—that you prefer to keep out of the cabin entirely. While it offers less capacity than a massive roof bag, its accessibility and space-saving footprint are unmatched. For those living in the tightest of mobile quarters, this is the most practical way to regain internal floor space.

MeeFar Roof Bag: Best for a Tight Budget

The MeeFar Roof Bag proves that reliable protection does not have to break the bank. It utilizes dual-seam technology and a thick, coated material that performs surprisingly well in heavy rain. It is the ideal entry-level choice for weekend warriors who need occasional extra storage but are not ready to commit to a top-tier, high-cost system.

While it lacks the sophisticated aerodynamics of pricier models, it does the job for occasional road trips. Just remember that because it is a budget-focused product, the zippers and straps require a bit more care and regular inspection. It is a solid, honest piece of gear that rewards the user for keeping it properly tensioned and cleaned.

ROLA Wallaroo Bag: Top Weatherproof Choice

The ROLA Wallaroo is defined by its robust, weatherproof construction and user-friendly expandability. Its standout feature is the ability to adjust the size based on current cargo needs, which keeps the bag taut and prevents the wind drag caused by partially filled, loose-fitting carriers. This adaptability makes it a versatile companion for changing seasons.

The material feels significantly thicker than standard cargo bags, providing a high level of confidence when driving through severe weather. It creates a vacuum-like seal that keeps dust and moisture at bay, protecting expensive camping equipment or bedding. If you frequently traverse environments with extreme humidity or heavy precipitation, this is the reliable barrier your gear needs.

Pack-Em-All: Best for RV Bumper Racks

For those using square RV bumper racks, the Pack-Em-All is a purpose-built solution that fits like a glove. Most rooftop bags are designed for cars, making them awkward to strap onto RV bumper systems; this bag eliminates that mismatch. It is built specifically to handle the vibrations and shifting of a rear bumper mounting position.

The attachment system is intuitive, preventing the sagging that often occurs when a non-specific bag is forced onto a bumper. Because it stays low and tucked behind the bumper, it rarely impacts your fuel efficiency or your sightlines. It is the most sensible choice for an RV owner who wants a “set it and forget it” storage solution for rear-mounted racks.

Roof vs. Hitch: Which Mount Is Right for You?

The choice between a roof or hitch mount fundamentally changes the handling of your rig. Rooftop bags keep gear out of the way but raise your center of gravity and increase wind resistance, which can impact fuel economy. Hitch-mounted bags, conversely, are easier to load but can affect rear clearance and may obscure your backup camera or taillights.

Consider the height of your RV carefully when evaluating roof options. Many campgrounds and gas stations have height restrictions that will make a rooftop carrier a liability. If you choose a roof mount, ensure you have a safe, sturdy ladder and a clear plan for how to secure the load without damaging the roof membrane or solar panels.

Safely Securing Your External Storage Bag

A storage bag is only as good as its mounting system. Always use the manufacturer-provided straps, but supplement them with high-quality cam-buckle tie-downs if the bag shows any signs of movement. Never use elastic bungee cords for heavy items; they will inevitably stretch and loosen, creating a significant road hazard.

Check your straps at every fuel stop, especially during the first few hours of a trip. Vibration on the road acts like a slow-motion shaker, loosening even the tightest knots and buckles over time. Periodically inspect the bag’s material for wear at the stress points where it contacts the rack to ensure you aren’t nearing a failure.

Waterproof vs. Water-Resistant: What to Know

The distinction between waterproof and water-resistant is vital when your gear is exposed to 60-mph winds and heavy rain. A water-resistant bag might handle a light mist, but prolonged exposure will eventually lead to damp clothing and ruined electronics. If the label says water-resistant, it is a safe bet that you should wrap your internal contents in heavy-duty plastic bags.

True waterproofing usually involves sealed seams, roll-top enclosures, and heavy-duty vinyl or PVC fabrics. Always lean toward overkill when storing sensitive items like sleeping bags or laptops. Investing in a dry bag to place inside your external carrier adds an essential second layer of protection that ensures your trip isn’t ruined by a single unexpected storm.

Packing and Weight Distribution Essentials

Weight distribution is the silent factor in vehicle safety. Always place your heaviest items at the bottom and center of the bag to keep the weight focused near the mounting points. Loading too much weight toward the outer edges of a roof bag can create a pendulum effect in corners, which puts undue stress on the bag and your vehicle’s roof structure.

Never exceed the maximum weight capacity of your roof rack or hitch receiver. Just because the bag looks like it can hold more does not mean your vehicle’s structure is rated for it. Keep a log of your “packed weight” to ensure you remain within the safety limits of your RV, keeping the handling predictable and the journey stress-free.

External storage bags are a powerful way to reclaim your interior living environment without the permanence of adding bulky hardware. By matching the right bag to your specific mounting system and keeping a keen eye on weight distribution, you can expand your capacity while maintaining the mobility that defines the nomadic lifestyle. Choose the setup that fits your travel style, and prioritize the integrity of your gear as much as the convenience of the storage itself.
