A strong RV hitch storage box adds secure, weather-conscious cargo space while fitting your receiver and leaving your existing storage usable. For a standard 2-inch receiver, the Buyers Products 1707020 offers a large 17-cubic-foot box; the Herc Outdoors model is explicitly designed for RVs and campers and includes a lock. The StowAway Max adds a swingaway frame for rear-door access.
This roundup also includes trailer tongue boxes, which mount differently and may suit A-frame trailers better than a receiver hitch. Compare mounting style, dimensions, capacity, and included hardware before choosing: a box described as a tongue box is not automatically a hitch-mounted cargo carrier, and receiver compatibility alone does not confirm fit on every RV.
The Buyers Products 1707020 is the strongest overall pick for a standard RV receiver when you want substantial, stated capacity: its 17-cubic-foot polyethylene chest mounts to a 2-inch receiver and includes a steel frame and 5/8-inch hitch pin. Choose the Herc Outdoors RV & Camper Hitch Mount Cargo Trunk if an RV-specific product with a key lock and water-resistant seal matters more than published dimensions or capacity. For rear-door access, the StowAway Max adds a swingaway frame and 16 cubic feet of storage.

Detailed Reviews: Best Storage Box For RV Hitch
#1 · Best Overall
1. Buyers Products Hitch Cargo Carrier
- Material: Plastic
- Material Type: Plastic
- Dimensions: 51"L x 23"W x 26"H
Best for: Large 2-Inch Hitch Cargo Box.
Why it ranks #1: Its 17-cubic-foot polyethylene chest fits a 2-inch receiver and includes a powder-coated steel frame and 5/8-inch hitch pin.
A 17-cubic-foot polyethylene chest rides on a hitch-mounted steel frame, adding substantial enclosed storage without using passenger space. Buyers Products includes a 5/8-inch hitch pin, and the carrier fits a 2-inch receiver. The dent-resistant box has a double-walled lid and is described as waterproof, making it suited to hauling gear outside the vehicle.
The 51-by-23-by-26-inch carrier offers a large cargo space for camping or utility gear, while its 76-pound listed weight is important to account for when handling and fitting it. The pre-drilled, powder-coated steel frame supports assembly and outdoor use, and the included 5/8-inch pin secures the assembly at a compatible 2-inch receiver. A high-density polyethylene chest with a double-walled lid provides dent-resistant, waterproof storage separate from the truck bed or passenger compartment.
- 17-cubic-foot cargo capacity.
- Fits a 2-inch receiver and includes a 5/8-inch hitch pin.
- Dent-resistant polyethylene chest has a double-walled lid.
- Pre-drilled, powder-coated steel frame is corrosion-resistant.
- The carrier weighs 76 pounds, making handling and installation more demanding.
Skip it if you need to swing a loaded carrier away from the rear doors; the StowAway MAX 024.3 has a swingaway frame.
Choose this Buyers Products carrier for large, enclosed gear storage on a vehicle with a 2-inch receiver. Its 76-pound weight and 51-by-23-inch footprint matter when planning installation and rear access.

#2 · RV-Specific Pick
2. Herc Outdoors Hitch Cargo Trunk
- Material: Steel
- Material Type: Steel
Best for: RV Gear for 2-Inch Receivers.
Why it ranks #2: It is designed for RVs and campers, fits a standard 2-inch receiver, and lists a key lock and water-resistant rubber seal.
Compatibility with a standard 2-inch receiver makes the Herc Outdoors cargo trunk an option for RVs, campers, and other equipped vehicles. Its lockable HD polyethylene box is intended for camping gear, fishing equipment, tools, coolers, and outdoor essentials. A water-resistant rubber seal helps protect stored items from moisture, while the included H10 mount supports hitch installation.
The standard 2-inch receiver fit gives owners of compatible RVs and vehicles a defined mounting interface, while the included H10 mount and small pan mount are part of the supplied setup. High-density polyethylene construction is described as rugged and weather-resistant, and the water-resistant rubber seal adds protection against moisture for stored gear. The key-lock cargo box secures the contents. Because the listing does not give dimensions or a capacity figure, assess your cargo and available space before choosing it.
- Fits a standard 2-inch receiver.
- Lockable cargo box includes a key lock.
- Water-resistant rubber seal helps protect against moisture.
- Intended for camping gear, fishing equipment, tools, and coolers.
- The listing gives no dimensions or capacity figure for planning cargo space.
Skip it if you need a published cargo volume and dimensions; the Buyers Products 1707020 lists 17 cubic feet and measures 51 by 23 by 26 inches.
Choose this Herc Outdoors trunk for RV or camper owners needing lockable, moisture-protected gear storage on a standard 2-inch receiver. Its intended uses are broad, but the listing omits dimensions and capacity.

3. StowAway Max Hitch Cargo Box
- Material: Plastic
- Material Type: Plastic
- Dimensions: 51"L x 23"W x 26"H
Best for: Swingaway Rear-Access Cargo.
Why it ranks #3: Its swingaway frame allows access to rear doors, liftgates, or tailgates without removing the carrier, and it provides 16 cubic feet.
A patented swingaway frame lets the StowAway MAX move aside for access to rear doors, liftgates, or tailgates without removing the carrier. Its 16 cubic feet of storage and 200-pound capacity add room for road trips, camping, and travel. The included package combines the cargo box, swingaway frame, hitch tightener, tail lights, and license plate bracket.
The 51-by-23-by-26-inch box provides a substantial cargo area, while its 16-cubic-foot volume and 200-pound capacity define the available storage and load limit. The swingaway frame addresses a common access workflow: move the carrier to reach rear doors or a tailgate instead of detaching it. Included tail lights and a license plate bracket support the carrier setup, and the hitch tightener is part of the supplied components. The listing identifies plastic construction and an ivory finish.
- Swingaway frame enables rear access without removing the carrier.
- 16 cubic feet of storage.
- 200-pound capacity.
- Includes tail lights, hitch tightener, and license plate bracket.
- Its 200-pound capacity sets a firm ceiling for heavier cargo loads.
Skip it if you need a stated 17-cubic-foot cargo volume; the Buyers Products 1707020 lists that capacity and fits a 2-inch receiver.
This StowAway suits travelers who need extra cargo room but still want access to rear doors or a tailgate. Keep its 200-pound limit in view, and account for the 51-by-23-inch box dimensions.

View on Amazon#4 · Aluminum Tongue Box
4. VEVOR Trailer Tongue Box
- Material: Aluminum
- Material Type: Aluminum
- Dimensions: 39"L x 16.5"W x 12"H
Best for: Lockable Aluminum Tongue Box.
Why it ranks #4: The lockable 39-by-16.5-by-12-inch aluminum box resists rust and wear, but its tongue mounting is not a receiver cargo carrier.
A 39-inch aluminum body gives the VEVOR trailer tongue box room for tools while keeping its listed weight to 16.3 pounds. Its lock and two included keys provide secured access, and the 5-bar patterned surface has a double-sided dusting process. The box is intended for trailer tongues and is listed for RV and flat-trailer use.
At 39 by 16.5 by 12 inches, this box provides a long, low storage shape for organizing tools on a trailer tongue; the included keys make its lockable closure usable without a separate key purchase. Thickened aluminum alloy and a 5-bar pattern are paired with stated rust and wear resistance, supporting outdoor trailer use. The 16.3-pound listed weight keeps the box relatively manageable during placement, while its 30-kilogram capacity sets a clear load boundary.
- Thickened aluminum alloy construction.
- Lockable closure includes two keys.
- 39-inch length provides a long tool-storage footprint.
- Surface is specified as rust- and wear-resistant.
- Its stated 30-kilogram capacity limits the load it can carry.
Skip it if you need a hitch-mounted cargo carrier with a large enclosed volume; the Buyers Products 1707020 provides 17 cubic feet.
This VEVOR suits RV and flat-trailer owners who want lockable aluminum tool storage on the tongue and value its long, low shape. Check the 39-by-16.5-inch footprint and 30-kilogram capacity against your storage needs.

5. Buyers Products Poly Tongue Box
- Material: Polyethylene
- Material Type: Polyethylene
- Dimensions: 19"L x 36"W x 17.5"H
Best for: A-frame Trailer Tool Storage.
Why it ranks #5: Its 36-inch polyethylene chest has a double-wall lid and weather-resistant zinc-plated hasp, but it is designed for A-frame trailers.
A molded, double-wall hinged lid gives this 36-inch Buyers Products tongue box a protective closure for tools carried on an A-frame trailer. Its high-density polyethylene body is dent-resistant and corrosion-resistant, while the zinc-plated hasp helps secure the contents. The layout targets equipment storage at the trailer tongue rather than a hitch-mounted cargo platform.
The 36-liter capacity offers a dedicated place for tools and equipment, and the 19-by-36-by-17.5-inch dimensions describe its footprint for planning tongue-area storage. Buyers specifies lightweight construction for easier mounting on A-frame trailers, making this a trailer-mounted option rather than one that occupies a vehicle receiver. The double-walled lid and weather-resistant zinc-plated hasp support protected, lockable storage; the polyethylene body adds dent resistance and corrosion resistance for outdoor use.
- High-density polyethylene body is dent-resistant.
- Double-walled hinged lid helps protect stored equipment.
- Weather-resistant zinc-plated hasp provides a lockable closure.
- Designed for mounting at the front of A-frame trailers.
- Its 36-liter capacity is limited for bulky camping gear.
Skip it if you need a large hitch-carried cargo area; the Buyers Products 1707020 offers 17 cubic feet and fits a 2-inch receiver.
Choose this Buyers Products box for tools that belong on an A-frame trailer tongue, especially when a lockable, weather-resistant lid matters. Its 36-liter capacity is better suited to equipment than bulky trip cargo.

6. BACLAUGH Aluminum Trailer Toolbox
- Material: Aluminum
- Material Type: Aluminum
- Dimensions: 48"L x 15"W x 15"H
Best for: Side-Handle Lockable Storage.
Why it ranks #6: The lockable aluminum toolbox includes a stainless steel security lock and key, but the listing does not establish 2-inch receiver compatibility.
Side handles give this BACLAUGH aluminum-coated toolbox a way to be carried or positioned, while its included stainless steel lock and key secure the contents. The listing identifies it for RVs, pickup trucks, trailers, and trucks, making it a broad-use storage box. Its stated 48-by-15-by-15-inch dimensions provide a long, narrow storage profile.
The 48-inch length and 15-inch width and height provide a defined space to assess against the available storage area on an RV, pickup, or trailer. Aluminum construction supports a metal-box format, and the side handles help when positioning or moving it. A stainless steel security lock and key provide the listed locking hardware for stored gear. The product is also described as waterproof, but the supplied details do not specify a capacity or mounting method, so plan around its dimensions and intended vehicle use.
- Aluminum construction.
- Side handles assist handling and positioning.
- Includes a stainless steel security lock and key.
- Listed for RVs, pickup trucks, trailers, and trucks.
- The listing provides no capacity figure for estimating how much gear it holds.
Skip it if you need a specified receiver mount or published capacity; the VEVOR JL-TB09-4 lists dimensions, capacity, and tongue-box use.
Consider this BACLAUGH box when side handles, lock-and-key security, and a long 48-inch format suit your RV or trailer storage area. Its listing leaves capacity and mounting details unspecified, so those needs require another option.

View on AmazonCheck receiver fit and rear clearance before buying
A 2-inch receiver label confirms the intended receiver size, but it does not establish that a carrier clears your RV’s rear equipment or opens where you need it to. The Buyers Products Hitch Cargo Carrier and Herc Outdoors Hitch Cargo Trunk both list 2-inch receiver compatibility; the StowAway Max adds a swingaway frame intended to provide access to rear doors, liftgates, or tailgates without removing the carrier. Still, measure the distance from your receiver to the rear door, spare tire, ladder, and bumper, then compare it with the carrier’s installed reach and box dimensions.
Those fit measurements are not supplied for every product here, so verify them with the manufacturer before purchase. Also check whether the box blocks lights or a license plate and whether your receiver’s permitted load accounts for the carrier and its contents.
Tongue boxes and hitch carriers solve different storage problems
A trailer tongue box mounts on the trailer tongue, while a hitch cargo carrier occupies a vehicle’s receiver; choosing the wrong mounting style can leave you with a box that cannot attach as planned. Buyers Products Poly Tongue Box is specified for A-frame trailers, and the VEVOR Trailer Tongue Box is described as a tongue-mounted storage solution. Neither listing establishes standard receiver mounting.
By contrast, the Buyers Products Hitch Cargo Carrier and Herc Outdoors Hitch Cargo Trunk specify a 2-inch receiver, while the StowAway Max is a hitch cargo carrier with a swingaway frame. This difference affects access and placement as well as compatibility: tongue storage stays on the trailer, while a receiver carrier uses the vehicle’s hitch.
Confirm the mounting location before comparing capacity or materials; a large tongue box is not a substitute for a receiver-mounted trunk.
How to Choose an RV Hitch Storage Box
Mounting style and receiver fit
Look first for a product that matches the mounting point you actually intend to use. The Buyers Products Hitch Cargo Carrier and Herc Outdoors Hitch Cargo Trunk both specify a 2-inch receiver; the StowAway Max is also identified as a hitch cargo carrier, but its supplied listing does not state a receiver size. By contrast, the Buyers Products Poly Tongue Box is made for A-frame trailers, and the VEVOR Trailer Tongue Box is a tongue-mounted model.
A receiver carrier suits buyers who need cargo outside the RV or vehicle, while a tongue box suits someone adding storage to a compatible trailer tongue. Check your receiver size and installation clearances rather than assuming that any trailer toolbox will fit a hitch.
Capacity and box dimensions
Choose a stated capacity that fits your gear, then compare the box dimensions with the space available behind your RV. The Buyers Products Hitch Cargo Carrier lists 17 cubic feet, while the StowAway Max lists 16 cubic feet. The Herc Outdoors model gives no capacity or dimensions in the supplied specifications, so buyers needing a precise volume should seek confirmation before selecting it.
Among tongue boxes, the Buyers Products Poly Tongue Box lists 36 liters, and the VEVOR box measures 39 by 16.5 by 12 inches. The larger stated cargo volumes favour road-trip gear, while compact dimensions may better suit limited trailer-tongue space.
Remember that exterior dimensions do not reveal usable interior space.
Weather protection, security, and access
Match the protection and access details to the gear you plan to carry. The Buyers Products Hitch Cargo Carrier is described as waterproof and has a double-walled lid; the Herc Outdoors Hitch Cargo Trunk lists a water-resistant rubber seal and key lock. The Buyers Products Poly Tongue Box also has a double-wall lid and weather-resistant zinc-plated hasp, while the VEVOR box includes a lock and keys.
For access to rear doors without removing a carrier, the StowAway Max has a swingaway frame. Buyers prioritizing stated weather protection can favour the sealed or waterproof descriptions, while those who regularly need rear access may favour the swingaway design.
Listings do not establish performance in specific weather conditions, so use the product’s stated protection as a guide, not a guarantee.
Which RV Hitch Storage Box Should You Choose?
Choose the Buyers Products Hitch Cargo Carrier if you want the largest stated receiver-mounted capacity here: it offers 17 cubic feet and fits a 2-inch receiver. Pick the Herc Outdoors Hitch Cargo Trunk if an RV- and camper-focused design, key lock, and water-resistant rubber seal matter most, but confirm its dimensions and capacity first. For frequent access to rear doors or a liftgate, the StowAway Max Hitch Cargo Box has a swingaway frame and 16 cubic feet.
If you need storage mounted on an A-frame trailer rather than the vehicle’s receiver, consider the Buyers Products Poly Tongue Box or VEVOR Trailer Tongue Box. The BACLAUGH Aluminum Trailer Toolbox is lockable, but its listing does not establish receiver fit, so verify mounting compatibility before choosing it for hitch use.

Frequently Asked Questions
How do I check whether a hitch cargo box will clear my RV’s rear doors, ladder, or spare tire?
Measure the distance from the receiver to nearby doors, ladders, and the spare tire, then compare it with the box and frame dimensions. Check whether the box obstructs opening doors or reaching equipment. A swingaway frame, such as the StowAway Max’s, can help with rear access, but confirm clearance on your RV.
How much weight can my RV’s receiver carry when a cargo box is loaded?
Check the receiver’s tongue-weight rating and your RV’s documentation, then include the cargo box’s weight and everything loaded inside it. The loaded setup must remain within the applicable limits. A product’s stated storage capacity does not establish how much weight your RV receiver can safely support.
How can I protect gear from rain, road spray, and dust inside a hitch cargo box?
Choose a box with a stated seal or weather-protection feature, and keep the lid fully closed and secured. The Herc Outdoors trunk is described as having a water-resistant rubber seal; the Buyers Products 1707020 listing describes a waterproof chest. No box should be assumed dustproof or fully weatherproof without confirming its specific details.
Can a trailer tongue box mount to an RV’s receiver?
Not necessarily. Tongue boxes are intended for trailer tongue or A-frame mounting, while receiver-mounted cargo boxes fit a vehicle’s hitch receiver. The Buyers Products Poly Tongue Box and VEVOR Trailer Tongue Box are tongue-box options; verify mounting compatibility before considering any tongue box for receiver use.
What should I verify before choosing a lockable cargo box?
Confirm the mounting type, dimensions, capacity, and access needs, then check exactly what the lock and weather-seal claims cover. The Herc Outdoors trunk is described as having a key lock and water-resistant seal, but its dimensions and capacity are not published in the supplied information, so confirm those before choosing it.
Final Words
For a standard 2-inch RV receiver and substantial stated capacity, the Buyers Products 1707020 is the strongest overall choice, with 17 cubic feet of storage. If access to rear doors matters, consider the StowAway Max and its swingaway frame. Choose the Herc Outdoors trunk for its RV-focused design, key lock, and water-resistant seal, while confirming its dimensions and capacity.
For A-frame mounting, consider a tongue box rather than assuming receiver compatibility.
