Herc Outdoors RV & Camper Hitch Mount Cargo Trunk
The Herc Outdoors Hitch Mount Cargo Trunk is built for durability and weather resistance, making it an excellent choice for pet owners who frequently travel in rugged environments. Its high-density polyethylene construction offers superior protection against the elements, while the lockable lid enhances security for pet gear and accessories. Compared to the Thule Santu, which emphasizes capacity and mobility, Herc Outdoors prioritizes outdoor toughness and security, but it is notably heavier and bulkier, which can make handling alone challenging. If you need a tough, weatherproof box that keeps pet gear safe during rough conditions, this model is a strong contender.
Pros:- Durable high-density polyethylene construction for outdoor use
- Water-resistant rubber seal protects gear from moisture
- Secure lockable design enhances safety

Cons:- Heavy and bulky, difficult to handle alone

- No internal organization features
Best for: Pet owners who need rugged, weatherproof storage for outdoor adventures or frequent camping trips.
Not ideal for: Those seeking a lightweight, easily portable cargo box or one primarily used for urban or short-distance travel.

Our verdict“This cargo trunk is ideal for rugged outdoor use, where durability and security outweigh ease of handling.”
Thule Santu Hitch Cargo Box, 99 lb Capacity, 9 cu ft
The Thule Santu Hitch Cargo Box makes sense for pet owners who need extra space and easy handling, especially if they’re also carrying bikes or other gear. Its 9 cubic feet capacity and 99-pound weight limit mean ample room for pet kennels, accessories, or supplies. The inclusion of wheels allows for easy rolling and positioning, a significant advantage when dealing with larger loads. However, compared to the Herc Outdoors trunk, it lacks weatherproofing and security features, so it’s better suited for dry conditions or short-term storage. Its compatibility with Thule bike carriers adds versatility for active travelers but limits its use with other rack systems.
Pros:- Large internal capacity for pet gear and accessories
- Wheels for easy maneuverability
- Compatible with Thule bike carriers
- Low-profile design for ergonomic loading
Cons:- Limited to Thule bike carrier compatibility
- No built-in lock or security features
- Less rugged outdoor protection
Best for: Pet owners who prioritize capacity, ease of transport, and multi-use functionality, especially those who combine pet gear with bikes or outdoor equipment.
Not ideal for: Those needing weatherproof, secure enclosures or owners seeking a dedicated pet gear box with internal organization features.
- Weight Capacity:99 lbs
- Internal Volume:9 cu ft
- Compatible With:Thule Epos, Thule EasyFold XT
- Fits Bikes:2-bike and 3-bike versions
Our verdict“Thule Santu is perfect for active pet owners seeking capacity and mobility, but it’s less suited for harsh outdoor environments or secure storage needs.”
How We Picked
Our selection process focused on products specifically designed for transporting pet gear via hitch-mounted cargo boxes. We prioritized durability, weather resistance, security, capacity, and ease of installation. We compared user reviews, manufacturer specifications, and the versatility of each model in typical outdoor and travel scenarios. Recognizing that pet gear can include everything from kennels to accessories, we looked for options that offer enough space and protection without sacrificing ease of handling or security. Our goal was to identify models that stand out in their category for different types of pet owners and travel styles.
Factors to Consider When Choosing Hitch Mounted Cargo Box For Pet Gear
Choosing the right hitch-mounted cargo box for pet gear depends on several key factors. First, consider the typical climate and outdoor conditions you’ll encounter, which influence whether weatherproofing and ruggedness matter most. Next, evaluate your capacity needs—how much gear, including kennels or accessories, you need to carry. Security features like locks may be critical if you frequently leave your gear unattended. Ease of handling, especially if you travel alone or need to reposition the box often, also plays a vital role. Lastly, compatibility with your vehicle and existing rack systems ensures a smooth setup. Clarifying these priorities will help narrow down your options effectively.
Durability and Weather Resistance
If you often travel in rough outdoor environments, a rugged, weather-resistant cargo box becomes essential. The Herc Outdoors model excels here, with high-density polyethylene that withstands rain, snow, and dirt, ensuring your pet gear stays dry and protected. Conversely, the Thule Santu is less weatherproof, making it better suited to dry, urban, or short-term use. Think about how often you’ll encounter harsh conditions—if durability is a top priority, lean toward the Herc Outdoors.
Capacity and Internal Organization
Assessing how much pet gear you need to carry is crucial. The Thule Santu offers a generous 9 cubic feet of space, accommodating larger kennels or multiple accessories, which is ideal for active families or multi-pet households. The Herc Outdoors trunk, while sturdy, has no internal organization to speak of, so you’ll need to plan for how to secure smaller items. If your gear is bulky or if you prefer a clean, organized storage space, Thule’s larger volume is a clear benefit, but it comes with less outdoor ruggedness.
Security Features
Security can be a deciding factor—especially if you park in unfamiliar areas. The Herc Outdoors trunk features a lockable lid, offering peace of mind that your pet gear won’t be tampered with. The Thule Santu lacks built-in locks, which could be a concern for unattended storage. For frequent camping or outdoor trips where leaving gear overnight is common, a lockable option provides extra safety.
Mobility and Ease of Handling
Transporting heavy cargo boxes can be challenging, especially if you’re alone. The Thule Santu’s wheels make repositioning simple, a significant advantage for active travelers who need quick access or to adjust positioning. The Herc Outdoors trunk, being heavier and bulkier, requires more effort to move and is less convenient if frequent repositioning is needed. Consider your physical capacity and how often you’ll need to handle the box when choosing between these options.
Compatibility and Installation
Ensure your vehicle’s hitch system matches the product’s specifications. The Herc Outdoors trunk fits any standard 2-inch receiver hitch, making it highly versatile. The Thule Santu is compatible with specific Thule bike carriers, limiting its use with other racks but providing seamless integration if you already own Thule gear. Match your existing setup and future needs to avoid compatibility issues down the line.
Frequently Asked Questions
Can I lock these cargo boxes for security?
The Herc Outdoors model includes a lockable lid, providing added security for pet gear and accessories when unattended. The Thule Santu does not feature built-in locks, so if security is a priority, it may require additional locking accessories or may not be suitable for unattended storage.
Are these cargo boxes weatherproof?
The Herc Outdoors trunk is designed with weather-resistant high-density polyethylene and rubber seals, making it suitable for all outdoor conditions. The Thule Santu, while durable, is not fully weatherproof and is better suited for dry conditions or short-term use in mild weather.
Will these fit on my vehicle?
The Herc Outdoors trunk fits on any standard 2-inch receiver hitch, making it broadly compatible with most vehicles. The Thule Santu is designed to work with specific Thule bike carriers, so compatibility depends on your existing rack system. Always verify your hitch size and rack compatibility before purchase.
How much weight can these boxes hold?
The Herc Outdoors trunk is designed to handle substantial outdoor gear, but specific weight limits are not stated—its durability suggests it can handle typical outdoor gear loads. The Thule Santu has a 99-pound capacity, suitable for bikes and lighter gear but less for extremely heavy or bulky pet kennels.
Which box is easier to handle alone?
The Thule Santu features wheels that make repositioning easier, especially when fully loaded. The Herc Outdoors trunk, being heavier and bulkier, is more challenging to handle alone, especially for those with limited strength or mobility.
Conclusion
For pet owners who frequently venture into rugged outdoor environments or need secure, weatherproof storage, the Herc Outdoors RV & Camper Hitch Mount Cargo Trunk makes a compelling choice. Those who prioritize capacity, easy maneuverability, and compatibility with bike carriers might find the Thule Santu a better fit, especially for active families or urban travelers. Careful consideration of your typical travel conditions, security needs, and handling preferences will guide you toward the best product for your pet gear transport.
