1. CURT 18100 HitchMate Cargo Carrier: Best Overall
In our evaluation, the CURT 18100 HitchMate Cargo Carrier stands out for its robust steel construction and generous 500-pound capacity. The 60×24-inch platform provides ample space for large coolers or stacked storage boxes, and the integrated tie-down loops make securing loads straightforward. Owner feedback consistently praises its stability on long trips, though some noted the powder coating can chip if not cared for.
However, this carrier is heavy and requires assembly, which may deter those seeking a ready-to-use solution. It also lacks a built-in ramp or enclosure, so you’ll need a separate weatherproof box or cover. We recommend it for RVers who prioritize maximum payload and have a sturdy hitch. Skip it if you want a lightweight, fully enclosed storage box.
- Large platform fits multiple storage boxes or gear
- Integrated tie-down loops for secure cargo
- Fits 2-inch receivers with anti-rattle bolt
Pros: Very high weight capacity; Durable powder-coated steel
Cons: Assembly required with multiple bolts
2. StowAway 2.0 Hitch Mount Cargo Carrier: Best Enclosed Box
The StowAway 2.0 is one of the most popular enclosed hitch boxes we researched. Its high-density polyethylene shell is UV-resistant and weather-tight, keeping gear dry even in heavy rain. The tilt-down feature allows you to access the contents without climbing onto the bumper, and the lockable lid adds security. Based on owner feedback, the 500-pound capacity is realistic for heavier items like tools or camping gear.
However, the box sits low and can scrape on steep driveways or off-road trails, reducing your departure angle. It also adds considerable weight to the hitch. We recommend it for highway or paved-road RVers who need secure, weatherproof storage. Skip it if you frequently travel on rough terrain or need to maximize ground clearance.
- Fully enclosed, lockable storage box
- Easy tilt-down access to cargo
- UV-resistant, weather-tight design
Pros: Weatherproof and lockable; Tilt-down mechanism simplifies loading
Cons: Reduces departure angle significantly
3. AA Products 58110 Hitch Cargo Carrier: Best Value
The AA Products 58110 offers a large 60×24-inch platform at a budget-friendly price, making it a strong value pick in our comparison. The steel frame features an e-coating that resists rust, though owner reports indicate it can wear faster than powder coat in harsh climates. The folding design is convenient for storage when not towing, and the included anti-rattle pin helps reduce noise.
On the downside, the platform has no raised edges, so items can slide off if not tied down securely. Assembly is straightforward but requires basic tools. We recommend this carrier for cost-conscious RVers who need a large, flat surface for lightweight cargo. Skip it if you need weather protection or a more durable finish.
- Affordable price point for the size
- Folding design for compact storage when not in use
- Includes anti-rattle hitch pin
Pros: Very good value for a large platform; Folds up for easy storage
Cons: E-coating is less durable than powder coat
4. MaxxHaul 50115 Hitch Mount Cargo Carrier: Compact and Lightweight
The MaxxHaul 50115 is a compact hitch carrier ideal for smaller vehicles or those with limited hitch space. Its 20×20-inch platform is best suited for a single storage box or a few bags, and the lightweight design makes it easy to handle. We found that it fits both 1.25-inch and 2-inch receivers, adding versatility. Owner feedback highlights its simplicity and sturdiness for light loads.
However, the small platform limits what you can carry, and the 500-pound capacity is misleading because the platform size prevents heavy items from being safely stacked. The safety score is lower due to potential instability if overloaded. We recommend it for RVers who only need to carry a small cooler or tool bag. Skip it if you need to haul bulky or heavy gear.
- Small footprint fits tight spaces
- Lightweight at 22 pounds
- Fits both 1.25 and 2 inch receivers
Pros: Easy to install and remove; Works with smaller hitches
Cons: Limited capacity for larger items
5. Curt 18107 Hitch Mount Cargo Carrier: Heavy-Duty Pick
The Curt 18107 is a heavy-duty platform carrier built for rugged use. Its steel construction with a textured powder coat is designed to withstand abuse, and the raised lip around the platform helps keep cargo from shifting. Based on our research, this carrier is popular among owners who haul firewood or large coolers. The anti-rattle bolt reduces noise on rough roads.
However, the weight (35 pounds) makes it cumbersome to install and remove, and the smaller 48×20-inch platform may not suit those needing maximum space. The value score is lower due to the higher price relative to similar-sized carriers. We recommend it for RVers who prioritize durability over weight and need a secure platform for heavy items. Skip it if you need a lightweight or larger platform.
- Raised lip helps secure cargo
- Textured powder coat resists scratches
- Fits 2-inch receivers with anti-rattle bolt
Pros: Very sturdy build; Raised edges prevent sliding
Cons: Heavy at 35 pounds
6. Black Widow 2500 lb Hitch Cargo Carrier: Highest Capacity
The Black Widow 2500 lb carrier is an aluminum platform that is surprisingly light for its claimed capacity. The folding design and included cargo net add convenience, but the 18×18-inch platform is quite small, making it more suitable for a single duffel bag or small cooler. Owner feedback indicates the cargo net is not very durable and can fray over time.
In our evaluation, the capacity rating seems optimistic given the small size; stacking heavy items could be unstable. The safety score reflects this concern. We recommend it for RVers who need a lightweight, temporary carrier for light items. Skip it if you need a large or heavy-duty storage solution.
- Aluminum construction is lightweight
- Folding design for storage
- Includes cargo net
Pros: Lightweight and easy to handle; Comes with a cargo net
Cons: Small platform limits utility
7. Keeper 85615 Hitch Cargo Carrier: Budget Pick
The Keeper 85615 is a no-frills hitch carrier that offers basic functionality at a rock-bottom price. The 20×20-inch steel platform is painted black, but owner reports indicate the paint can chip and rust within months in wet climates. Assembly is simple, and the included tie-down hooks are useful for securing cargo.
However, the lower durability and safety scores reflect the potential for rust and limited stability with heavy loads. We recommend it for occasional use with lightweight gear, such as a small cooler or camping chairs. Skip it if you need a long-term, weather-resistant solution or plan to carry heavy items regularly.
- Lowest price in our comparison
- Simple bolt-on assembly
- Includes tie-down hooks
Pros: Very affordable; Decent size for the price
Cons: Paint finish can rust quickly
Frequently Asked Questions
Can I use a hitch storage box with a bumper-mounted spare tire?
Yes, but you may need a hitch extender or offset adapter to clear the spare tire. Ensure the combined weight of the box and cargo does not exceed your hitch’s rating, and check that the extension does not increase leverage beyond safe limits.
How much weight can an RV hitch storage box safely carry?
Most hitch carriers are rated for 500 pounds, but you must also consider your vehicle’s tongue weight rating and the receiver’s class. Always stay within the lowest rating among your hitch, receiver, and carrier. Overloading can cause sway or damage.
Will a hitch storage box affect my RV's departure angle?
Yes, especially with enclosed boxes that hang low. This can cause scraping on steep driveways or off-road terrain. If you travel on rough roads, consider a platform carrier that sits higher or a box with a tilt-up design.
Do I need a locking hitch pin for security?
While not mandatory, a locking hitch pin is highly recommended to prevent theft of the carrier and your cargo. Many carriers include a standard pin, but upgrading to a lockable one adds peace of mind.
Can I carry a generator in a hitch storage box?
Yes, but ensure the box is well-ventilated and the generator is turned off and cool before loading. Weight must be within the carrier’s capacity. Some enclosed boxes may trap heat, so check manufacturer guidelines.
Our Verdict
After comparing specifications, owner feedback, and safety considerations, our top pick is the CURT 18100 HitchMate Cargo Carrier for its balance of capacity, durability, and ease of use. For those needing a fully enclosed, weatherproof solution, the StowAway 2.0 is a close runner-up. Choose based on your need for open vs. enclosed storage and typical terrain.
