When I compare rated swing away hitch cargo carriers, I look for a useful combination of rear access, stated load capacity, receiver compatibility, and storage suited to the gear being carried. The StowAway Max is my pick for enclosed space, offering 16 cubic feet and a 200-pound rating; the 320-pound swing-away adapter stands out for buyers pairing an adapter with a compatible rack; and the StowAway Standard makes more sense for those who want an enclosed box with a smaller footprint. The main tradeoffs are clear: complete cargo boxes cost you weight and bulk, while adapters need a separate compatible carrier and careful attention to the combined load and vehicle limits.

I have ranked these options by how directly they solve a cargo-access problem, how much verified capacity and useful functionality the supplied details support, and how clearly their fit requirements are stated. These products are not interchangeable: two are enclosed StowAway boxes, while the other three are swing-arm adapters. I would check the receiver size, vehicle tongue-weight limit, carrier rating, and clearance before choosing any of them.

Key Takeaways
- For enclosed storage: The StowAway Max has 16 cubic feet of weather-resistant box space and a 200-pound load rating.
- For the highest stated adapter capacity: The 320-pound model fits a 2-inch receiver and offers 90- or 130-degree swing positions, but it is not for towing or recovery.
- For a smaller enclosed box: The StowAway Standard holds 12.5 cubic feet and weighs 94 pounds, 5 pounds less than the Max.
- For a defined pivot range: The Upgrade adapter swings from 0 to 105 degrees and lists a 49.8-inch extension, with vehicle compatibility checks required.
- Check the whole setup: Receiver fit alone does not establish safe capacity; compare the adapter, rack or carrier, vehicle tongue-weight rating, and loaded weight.

More Details on Our Top Picks
Max Hitch Cargo Box with Swingaway Frame | Black
The StowAway Max is my strongest all-around choice for buyers who want a complete, enclosed cargo solution rather than a swing adapter to build around. Its 16 cubic feet of space is the largest stated box volume in this lineup, giving it an advantage over the Standard when luggage, camping supplies, or bulky equipment need to stay out of the cabin. Its 200-pound load rating matches the Standard’s, so the added room is not a higher payload allowance.
The swingaway frame is the central reason to choose it over a fixed hitch box: it moves the cargo box away from the vehicle so the rear door, hatch, or tailgate can be reached without taking the carrier off. The keyed latch, hitch tightener, LED taillights, and lit license plate bracket also make this a more complete package than the bare swing-arm adapters. Its impact-resistant polymer construction and water-resistant description suit gear that needs protection from road exposure, though water resistance should not be read as a guarantee against every leak or weather condition.
The compromise is its 99-pound product weight and substantial 51-by-23-by-26-inch size. It is heavier and roomier than the 94-pound Standard, so storage and installation deserve planning. Buyers who only need a pivot for a separate bike rack should skip this box and compare the adapters instead. I would also check loaded weight against vehicle tongue-weight limits, not rely only on the box’s 200-pound rating.
Pros:- Largest listed enclosed volume here at 16 cubic feet.
- Swingaway frame allows access to rear doors, hatch, or tailgate without removing the box.
- Includes a keyed locking latch, hitch tightener, LED taillights, and lit plate bracket.
- Water-resistant, impact-resistant polymer shell with a 200-pound load rating.
Cons:- At 99 pounds, it is the heaviest listed product in this group.
- The 200-pound rating matches the smaller Standard rather than increasing with the box volume.
- Its large footprint calls for more storage space and a careful vehicle-fit check.
Best for: Drivers who want a large enclosed hitch box, regular access to the rear of the vehicle, and integrated locking and visibility features.
Not ideal for: Buyers seeking a light, compact adapter for an existing rack or anyone unable to store and handle a 99-pound cargo box.
- Type:Enclosed hitch cargo box with swingaway frame
- Volume:16 cubic feet
- Dimensions:51 × 23 × 26 inches
- Item weight:99 pounds
- Materials:LLDPE and steel
- Security and visibility:Keyed latch, hitch tightener, LED taillights, and lit license plate bracket
- Weather description:Water resistant
Our verdict“I recommend the Max for buyers who value the most enclosed storage in this comparison and can accommodate its weight and size.”
Swing Away Hitch Adapter, 320 lb Capacity, Fits 2-Inch Receiver
Among the standalone swing-arm options, this adapter has the highest stated capacity: 320 pounds. That makes it the most compelling pick here for a buyer whose compatible rack and vehicle can support a heavier combined setup. Unlike the StowAway Max and Standard, it is not an enclosed cargo carrier; it supplies the pivoting connection, so you must provide a compatible rack or carrier and confirm its rating as part of the full system.
The arm locks at 90 or 130 degrees, giving the user two access positions for reaching a tailgate or cargo area. It also includes a hitch tightener and locking pin, useful details that are not listed for every adapter in this group. At 35.2 pounds, it is much lighter than either enclosed StowAway box, though still substantial enough that handling and installation may take effort.
Its limits are especially important: it fits a 2-inch receiver and is explicitly not intended for towing or recovery. The stated 320-pound figure is not a reason to exceed the vehicle’s tongue-weight rating, the rack’s capacity, or any applicable accessory limit. Compared with the 250-pound 180-degree adapter, this model offers a higher listed capacity and defined locking positions, but it gives less rotational travel than a full 180-degree swing. I would skip it if the rack is not confirmed compatible or rear access requires a wider opening than its positions provide.
Pros:- Highest stated adapter capacity in this lineup at 320 pounds.
- Locks at 90 or 130 degrees for rear access.
- Includes a locking hitch pin and hitch tightener.
- At 35.2 pounds, weighs far less than either enclosed box.
Cons:- Requires a separate compatible rack or carrier.
- Limited to 2-inch receivers and is not for towing or recovery.
- The listed capacity does not replace vehicle, rack, or tongue-weight limits.
Best for: Owners of compatible 2-inch receiver setups who need a swing adapter with a higher stated capacity and two defined access positions.
Not ideal for: Anyone needing a complete enclosed carrier, a 180-degree pivot, or an adapter for towing, recovery, or a receiver other than 2 inches.
- Type:Swing-away hitch adapter
- Receiver size:2 inches
- Stated capacity:320 pounds
- Swing positions:90 or 130 degrees
- Product weight:35.2 pounds
- Included attachment features:Locking pin and hitch tightener
- Use limitation:Not for towing or recovery
Our verdict“I would choose this adapter when a compatible 2-inch setup needs the highest stated capacity here and two practical swing positions.”
StowAway Standard Cargo Carrier with SwingAway Frame for 2-Inch Hitch, Black
The StowAway Standard is the easier enclosed-box choice to justify when the Max’s extra volume is more than you need. It provides 12.5 cubic feet and a 200-pound rating, so its payload figure is the same as the larger Max despite the smaller footprint. At 49 by 21 by 24 inches, it takes up less space than the Max and weighs 94 pounds, a modest reduction that may help with handling but does not make it a lightweight carrier.
Like the Max, its swingaway frame preserves access to the rear of the vehicle, and its locking latch, taillights, and license plate bracket make it a ready-to-use enclosed unit rather than just an adapter. A drain plug is a practical addition for cleaning. For buyers choosing between the two boxes, I would pay attention to how much gear they actually need to carry: the Max gives 3.5 more cubic feet, while the Standard saves 5 pounds and has smaller listed dimensions.
The chief tradeoff is that this remains a heavy, hitch-mounted box requiring a 2-inch hitch. It also offers less storage than the Max without a higher load rating, so it is not the right pick if every bit of enclosed volume matters. Compared with the adapters, it avoids the extra step of sourcing a compatible rack, but it is bulkier and less flexible for different cargo accessories. I would choose it for regular luggage or gear trips, not for someone looking for a modular rack connection.
Pros:- Offers 12.5 cubic feet of enclosed storage with a 200-pound rating.
- Swingaway frame provides rear access without removing the box.
- Includes a locking latch, taillights, license plate bracket, and drain plug.
- Smaller and 5 pounds lighter than the StowAway Max.
Cons:- Still weighs 94 pounds and may be awkward to handle alone.
- Requires a 2-inch hitch.
- Provides less volume than the Max while sharing its 200-pound rating.
Best for: Buyers who want an enclosed, swing-away cargo box but prefer a smaller footprint than the StowAway Max.
Not ideal for: People needing maximum enclosed volume, a lightweight carrier, or an adapter to use with an existing rack.
- Type:Enclosed hitch cargo carrier with SwingAway frame
- Hitch size:2 inches
- Volume:12.5 cubic feet
- Dimensions:49 × 21 × 24 inches
- Item weight:94 pounds
- Material and weather description:Plastic; water resistant
- Included features:Locking latch, taillights, license plate bracket, and drain plug
Our verdict“I recommend the Standard when enclosed storage and swing-away access matter more than maximizing volume.”
Swing Away Hitch Adapter for 2 Inch Receiver, 180° Hitch Swing Arm
This adapter is the most direct match for buyers who prioritize a 180-degree swing and already own a compatible rack or cargo platform. It supports up to 250 pounds, placing it above the Upgrade adapter’s 220-pound rating but below the 320-pound model. Unlike the StowAway boxes, it does not add enclosed storage by itself; its role is to move a separate accessory out of the way so the vehicle’s rear can be reached.
The reinforced steel construction and corrosion-resistant finish suit regular outdoor use, while its full stated arc may be useful when a partial opening is not enough to reach a hatch or tailgate. The description lists a standard 2-inch receiver fit, which is straightforward, but it does not provide a product weight, extension dimension, or specific locking-position details. Compared with the 320-pound adapter, it offers more rotational travel but a lower stated capacity; compared with the Upgrade, its pivot range is broader on paper, while the Upgrade gives a defined 49.8-inch extension and 0-to-105-degree range.
I would not choose it solely on the 250-pound figure. The complete load includes the adapter, rack, and cargo, and the vehicle’s tongue-weight limit may be lower. Its 2-inch receiver restriction rules it out for other receiver sizes, and the product description warns that fit depends on vehicle type. Buyers who want a complete weather-resistant cargo box should choose one of the StowAway models instead. This is a focused access component, not a complete cargo-carrying solution.
Pros:- Listed 180-degree rotation for broad rear access.
- Supports up to 250 pounds according to the supplied description.
- Reinforced steel construction with a corrosion-resistant finish.
- Designed for use with compatible bikes, gear, or cargo accessories.
Cons:- Requires a separate rack or cargo carrier.
- Fits only 2-inch receivers and may not suit every vehicle.
- Product weight and detailed extension dimensions are not provided.
Best for: Owners of a compatible 2-inch receiver and rack who need a wide swing arc to reach the rear of the vehicle.
Not ideal for: Buyers wanting an enclosed box, a higher stated rating than 250 pounds, or a product with fully documented dimensions and vehicle fit.
- Type:Swing-away hitch adapter
- Receiver size:2 inches
- Rotation:180 degrees
- Stated capacity:250 pounds
- Material:Reinforced steel
- Finish:Corrosion-resistant
- Compatible use:Compatible bike racks, gear, or cargo carriers
Our verdict“I would select this adapter when a 180-degree swing matters more than the higher capacity offered by the 320-pound model.”
Upgrade Swing Away Hitch Adapter for 2 Inch Hitch Receiver, 220 LB Capacity
The Upgrade adapter suits buyers who want the swing mechanism specified with more detail than the 180-degree model provides. Its 0-to-105-degree pivot range and 49.8-inch extension give shoppers concrete dimensions to compare with a vehicle’s hatch, bumper, and accessory layout. It is rated to 220 pounds, less than the 250-pound and 320-pound adapters, so I place it lower for buyers focused on capacity rather than fit geometry.
It is designed for a 2-inch receiver and can be paired with compatible bike racks or cargo carriers. The supplied description calls installation easy and says parts come pre-assembled, but I would still treat vehicle compatibility as a required check: the product specifically notes that some models, including the LR4, may not be suitable. Its steel construction and foldable design offer a practical storage angle, although its weight is not specified, making it harder to judge handling against the 35.2-pound 320-pound adapter.
Compared with the 180-degree adapter, this one provides a narrower maximum arc but a stated extension length and pivot-shaft dimension. Compared with either StowAway box, it is a modular component rather than a ready-made enclosed carrier. That can make sense if you already have a compatible accessory and need a defined swing path, but the 220-pound rating and vehicle-specific fit caveat narrow its appeal. I would skip it if the required opening is wider than 105 degrees or the combined setup exceeds any component or vehicle limit.
Pros:- Lists a 0-to-105-degree pivot range and 49.8-inch extension.
- Rated for loads up to 220 pounds.
- Pre-assembled parts are described as supporting straightforward installation.
- Foldable design can help with storage when not in use.
Cons:- Lower stated capacity than the other three adapters in this lineup.
- Vehicle fit is not universal; the description names the LR4 as an example that may not fit.
- Product weight is not specified.
Best for: Buyers with a compatible 2-inch receiver who need a defined extension and pivot range for a separate rack or carrier.
Not ideal for: Anyone seeking the highest capacity, a complete cargo box, or a fit that has not been confirmed for their vehicle.
- Type:Swing-away hitch adapter
- Receiver size:2 inches
- Maximum load capacity:220 pounds
- Pivot range:0–105 degrees
- Extension length:49.8 inches
- Pivot shaft diameter:3.15 inches
- Construction and storage:Steel; foldable design
- Weight:Not specified
Our verdict“I recommend the Upgrade adapter when its documented 105-degree pivot and extension suit the vehicle better than a wider swing arc.”
How We Picked
I ranked these five options around the specific job implied by the title: carrying cargo behind a vehicle while still allowing access to the rear. I gave weight to the stated load rating, the useful range or positions of the swing arm, and whether the product is a complete carrier or only an adapter. An enclosed box has a different role from an adapter that needs a separate rack, so I did not treat cubic feet and adapter capacity as directly comparable measures.
I also looked at practical ownership differences in the supplied specifications: receiver size, dimensions, product weight, included security or visibility features, and stated limits. The Max and Standard earn their places as ready-to-use enclosed cargo options; the adapters are ranked by their documented capacity and access details. Missing information matters too: when a product description does not provide its own weight or a broad compatibility claim, I call that out rather than assuming a fit. These are feature-based editorial picks, not claims of hands-on testing. Buyers should verify vehicle, receiver, and accessory limits before loading.

Factors to Consider When Choosing Rated Swing Away Hitch Cargo Carriers
I would start by deciding whether you need an enclosed cargo box or a swing-away adapter. The box carries gear and provides storage; the adapter creates a pivot for an additional rack or carrier. After that, match the swing path and load limits to your vehicle rather than choosing by a single capacity number.
Complete box or adapter?
The StowAway Max and Standard are complete enclosed carriers, with listed volume, weather-resistant construction, and their own swingaway frames. They make sense when luggage or camping gear needs a contained space. The three other products are adapters: they require a compatible rack or carrier, so their stated capacities do not tell you the total load the entire setup can safely carry. I would compare the whole assembly, including accessory weight and cargo, before making a decision.
Match the swing arc to the vehicle
A wider arc may provide more room to reach a hatch or tailgate, but the vehicle’s shape, bumper, and mounted accessory affect clearance. The 180-degree adapter offers the broadest stated rotation; the 320-pound adapter locks at 90 or 130 degrees; and the Upgrade lists a 0-to-105-degree range with a 49.8-inch extension. I would measure the space needed for rear access and confirm the carrier clears the vehicle through its swing before relying on a listed angle alone.
Read capacity as a system limit
The product rating is only one part of the load calculation. Check the adapter or carrier limit, the separate rack’s limit, and the vehicle’s hitch and tongue-weight ratings. The lowest applicable limit governs the setup, and cargo weight needs to be included. The Max and Standard each list a 200-pound load rating; the adapters range from 220 to 320 pounds, but those adapter figures do not grant a vehicle more carrying capacity.
Account for weight and storage
The two enclosed boxes weigh 94 and 99 pounds before cargo, which can make installation and off-season storage challenging. The 320-pound adapter lists a 35.2-pound weight, while the other adapters’ weights are not supplied. I would think about whether the carrier will stay mounted, where it will be stored, and whether help is needed to fit or remove it. A slightly smaller box may be easier to manage, but the Standard is still a heavy accessory.
Check receiver fit and intended use
All three standalone adapters are specified for a 2-inch receiver, and the Standard also lists a 2-inch hitch. Do not assume a universal vehicle fit from a receiver-size match: hitch class, clearance, accessory compatibility, and manufacturer restrictions still matter. The 320-pound adapter specifically excludes towing and recovery. These products are intended to carry cargo or compatible racks, not to serve as a towing or recovery connection.
Compare protection and useful accessories
An enclosed box can keep cargo contained and out of open-air exposure, while an adapter leaves the choice of rack or cargo platform to you. The Max includes a keyed latch, taillights, hitch tightener, and illuminated plate bracket; the Standard lists a locking latch, taillights, plate bracket, and drain plug. For any setup, confirm that lights and the license plate remain visible and that cargo is secured. The adapters’ descriptions do not list the same integrated box features, so buyers may need to evaluate their chosen carrier separately.
Frequently Asked Questions
What does a swing-away hitch cargo carrier do?
A swing-away carrier or adapter pivots cargo away from the vehicle to create access to a rear hatch, door, or tailgate. Some products, such as the StowAway Max and Standard, combine the pivoting frame with an enclosed cargo box. The three adapters in this roundup provide the swing mechanism but need a separate compatible rack or carrier.
Which option offers the most enclosed cargo space?
The StowAway Max lists 16 cubic feet, compared with 12.5 cubic feet for the StowAway Standard. Both are rated for 200 pounds, so the Max offers more room rather than a higher stated load rating. I would choose between them based on how much gear needs to fit and whether the Max’s larger dimensions and 99-pound weight are manageable.
Does an adapter’s capacity determine how much my vehicle can carry?
No. The adapter rating is only one limit in the setup. You also need to check the vehicle’s hitch and tongue-weight limits, the rack or cargo carrier’s rating, and the weight of the adapter and cargo. Follow the lowest applicable limit, and confirm compatibility with the vehicle and each accessory before loading.
Can these swing-away adapters be used for towing?
The 320-pound adapter’s supplied description specifically says it is not for towing or recovery. The other adapters are described for cargo, gear, bike racks, or compatible carriers, not as towing equipment. I would use them only for their stated accessory-carrying purpose and follow the product maker’s instructions.
How do I know whether a swing-away carrier will fit my vehicle?
Start with the receiver size and check the product’s stated vehicle restrictions, then verify accessory compatibility, hitch and tongue-weight limits, and clearance around the bumper and rear door. The Upgrade adapter’s description warns that some vehicles may not fit, and a 2-inch receiver match alone does not establish compatibility. I would confirm that the carrier can swing through its full intended path without contacting the vehicle.
Conclusion
For buyers who want a complete enclosed carrier with the most listed storage, I recommend the StowAway Max, provided its 99-pound weight and larger footprint suit the vehicle and storage space. If a more compact enclosed box is the priority, the StowAway Standard keeps the same 200-pound rating in a smaller package. For owners using a separate compatible rack, I would choose the 320-pound adapter when its 90- or 130-degree positions provide enough access; the 180-degree adapter is a better match when wider rotation matters more than the highest listed capacity. The Upgrade makes sense when its defined 105-degree range and extension fit the setup. Before buying, I would confirm receiver fit, vehicle clearance, accessory compatibility, and the lowest load limit across the entire system.
