We’ve all been there. The night before a much-anticipated family vacation, the scene is one of controlled chaos. Suitcases, coolers, sleeping bags, and a mountain of “just-in-case” items are piled in the hallway. You look at your SUV, confident in its size, only to realize you’ve fundamentally misjudged the physics of packing. Thus begins the frustrating game of trunk Tetris, a battle of wills where every cubic inch is contested. Seats are folded, items are crammed into footwells, and rear visibility becomes a distant memory. This isn’t just an inconvenience; it compromises comfort and safety on the road. The alternative—leaving essential gear behind—is equally unappealing. This is the precise moment when the search for a better hauling solution begins, a quest to reclaim your vehicle’s interior and travel with everything you need, not just what you can fit.

What to Consider Before Buying a Hitch Cargo Carrier
A hitch cargo carrier is more than just a metal basket; it’s a key solution for unlocking your vehicle’s true hauling potential. For families, adventurers, and anyone who’s ever had to choose between bringing the camping gear or the extra luggage, these carriers are transformative. They extend your storage space externally, keeping bulky, dirty, or awkwardly shaped items out of your clean interior. This not only maximizes passenger comfort but also enhances safety by keeping the driver’s sightlines clear and preventing loose items from becoming projectiles during a sudden stop. The main benefits are clear: expanded capacity, improved interior organization, and the versatility to transport everything from camping equipment to home improvement supplies.
The ideal customer for this type of product is someone facing a recurring storage deficit, typically the owner of an SUV, van, or truck with a 2-inch hitch receiver who frequently embarks on family road trips, camping excursions, or needs to haul gear for hobbies. However, it might not be suitable for those who primarily drive small sedans without a hitch, or for individuals who are unable to lift and maneuver a heavy piece of equipment (the carrier itself can weigh over 60 pounds). For those without a hitch or who prefer a different approach, a rooftop cargo box or a simple roof rack basket might be a more fitting alternative. It’s crucial to assess your vehicle, your physical capabilities, and your typical cargo before committing.
Before investing, consider these crucial points in detail:
- Dimensions & Space: It’s not just about the numbers; it’s about usable space. A carrier’s length and width determine what you can carry. The Mockins XXL 70″x30″ Cargo Carrier w/ Waterproof Bag offers a massive platform, ideal for multiple large coolers or bins side-by-side. Also, consider the height of the side rails (6 inches in this case), which help contain your cargo, and whether the design will interfere with your vehicle’s exhaust pipes or liftgate.
- Capacity/Performance: The weight capacity is a critical safety metric. A 500-pound limit is standard and robust for most applications, but you must factor in the weight of the carrier itself against your vehicle’s tongue weight limit. Performance also includes features like a raised shank for better ground clearance—essential for driveways and uneven terrain—and an anti-rattle stabilizer, which is non-negotiable for a quiet and secure ride.
- Materials & Durability: Most hitch carriers are made of steel for its strength and affordability. Look for a powder-coated or corrosion-resistant finish to protect against rust and the elements. While aluminum options are lighter, steel, like the alloy steel used here, offers superior rigidity and durability, which is paramount when you’re carrying hundreds of pounds at highway speeds. Pay close attention to the quality of the welds, as this is a common point of failure.
- Ease of Use & Maintenance: Consider the entire lifecycle. How difficult is the initial assembly? Does it have a folding feature to save space when not in use? How easy is it to attach and remove from your vehicle? Long-term care involves checking bolts for tightness before each trip and touching up any scratches in the paint to prevent rust. An all-inclusive kit with straps, locks, and a bag simplifies the user experience significantly.
Keeping these factors in mind, the Mockins XXL 70″x30″ Cargo Carrier w/ Waterproof Bag stands out in several areas, particularly its all-inclusive nature and sheer size. You can explore its detailed specifications here.
While the Mockins XXL 70″x30″ Cargo Carrier w/ Waterproof Bag is an excellent choice, it’s always wise to see how it stacks up against the competition. For a broader look at all types of external storage, we highly recommend checking out our complete, in-depth guide:
- HEAVY DUTY STEEL CONSTRUCTION: 1 Piece construction with matt black powder coating finish that resists the elements, rust and scratches.
- DURABLE BUILD - Tubular steel in black epoxy powder coating to promote high strength and a lightweight design. and covered in a rust free coating. It is rated for 200 lbs
- 【LARGE STORAGE CAPACITY】Free up space in your vehicle with this roof rack cargo basket that can hold up to 200 Lbs. Overall dimensions include: 46"(L) x 36"(W) x 5"(H)
Unboxing the Behemoth: First Impressions and Key Features
The arrival of the Mockins XXL 70″x30″ Cargo Carrier w/ Waterproof Bag is an event in itself. The box is large and heavy, tipping the scales at over 65 pounds, immediately signaling that this is a substantial piece of hardware. Unpacking it reveals a formidable collection of black and red powder-coated steel parts, a massive folded-up vinyl cargo bag, and a dizzying array of smaller boxes containing lights, straps, locks, and hardware. The initial impression is one of robust, heavy-duty construction. The steel tubes feel thick and the mesh floor is solidly welded. However, echoing the sentiments of some users, we did notice a few minor scuffs and scratches on the finish right out of the box—cosmetic blemishes on a utility item, but worth noting for those who expect perfection. The sheer number of components can be intimidating; this is clearly not a “plug-and-play” accessory. It’s a full kit that requires dedicated time for assembly, a project that promises immense capability once completed.

A Deep Dive into the Mockins XXL Carrier’s Real-World Performance
A spec sheet can only tell you so much. To truly understand the Mockins XXL 70″x30″ Cargo Carrier w/ Waterproof Bag, we had to build it, load it, and take it on the road. We tested its assembly process, its on-road stability, its immense capacity, and the utility of its all-inclusive accessory package to see if it lives up to its promise as the ultimate road trip extender.
Assembly and Installation: A Test of Patience and Strength
Let’s be perfectly clear: assembling this carrier is a significant undertaking. While some users report it being straightforward, our experience and a significant number of customer reviews point to a process that requires time, a decent set of tools (specifically wrenches, which are not included), and a fair bit of muscle. The instructions, though filled with pictures, can be difficult to decipher due to their dark print quality. We encountered the most common issue reported by users: a slight misalignment between the two halves of the basket and the central connection plate. This required us to use considerable force—and a second person—to get the bolt holes to line up, causing the bolts to go in at a slight angle. This is a frustrating first step that can set a negative tone.
Wiring the integrated lights is another hurdle. Snaking the wires through the steel frame is a tedious task, and the included connectors may require some fiddling to ensure a secure connection. Furthermore, as one astute user pointed out, the back of the light housing protrudes into the cargo area, creating a potential snag point that could damage the wiring plug when loading gear. The folding mechanism is held in place by two large pins with retaining clips. These pins are a very tight fit, and we found it impossible to insert or remove them by hand. A rubber mallet became an essential tool for the job, which raises concerns about the ease of folding and unfolding the carrier on the go. While the end result is a sturdy, feature-rich carrier, buyers must be prepared for an assembly process that is more of a weekend project than a 30-minute task.
On the Road: Real-World Capacity and Stability
Once assembled and mounted, the true purpose of the Mockins XXL 70″x30″ Cargo Carrier w/ Waterproof Bag becomes brilliantly clear. The sheer scale is impressive. The 70-inch length and 30-inch width create a platform that can swallow gear whole. We easily fit four large storage bins across its floor with room to spare. For a family road trip, this translates to multiple suitcases, a large cooler, and various bags—all living outside the vehicle. This is where the carrier shines brightest, liberating an enormous amount of interior space.
The included hitch stabilizer is not an optional accessory; it is absolutely essential. Once tightened, it does an admirable job of eliminating the majority of the wobble and sway at the connection point, making the carrier feel like a solid extension of the vehicle. During our test drive on highways and bumpy back roads with a moderate load (around 250 lbs), the carrier felt secure. We can see why one user confidently completed a 4,900-mile journey and another a 14-hour drive in bad weather. However, a critical warning must be issued regarding its use on RVs. Multiple users have reported catastrophic failures, including bending frames and failing welds, even with loads well below the 500-pound limit. The extended distance from the rear axle on an RV creates different, more intense forces that this carrier does not seem engineered to handle. For SUVs and trucks, it performs well, but we strongly advise against purchasing it for use on a travel trailer or motorhome.
The All-Inclusive Kit: Is the Bag and Accessory Package Worth It?
The “set” aspect of this product is arguably one of its biggest selling points. Chief among the accessories is the 40 cubic foot waterproof cargo bag. This is not a flimsy afterthought. It’s constructed from a thick, abrasion-resistant vinyl material reminiscent of whitewater rafting bags. The waterproof zipper is protected by a generous 2-inch flap secured by long strips of Velcro, creating a highly effective barrier against the elements. A user who drove 14 hours through severe weather and arrived with perfectly dry luggage provides the best possible testament to its effectiveness. This bag alone is a high-value item that solves the problem of protecting your gear from rain, dirt, and road grime.
The inclusion of three heavy-duty ratchet straps, three buckle straps, a hitch lock, a combination lock for the bag, and a storage bag for the carrier bag itself rounds out an incredibly comprehensive package. This saves the buyer the time and money of having to source these essential items separately. The integrated lights and license plate bracket are crucial safety and compliance features that many other carriers lack, making this a road-legal solution right out of the box. While there are some design quibbles, like the aforementioned light wiring, the overall value proposition of the complete kit is undeniable. If you want a one-and-done hauling solution, the Mockins XXL package is incredibly compelling.
What Other Users Are Saying
Digging into the collective experience of other buyers reveals a consistent, if divided, story. On the positive side, the praise is often effusive. One owner of a 2024 Expedition Max called it an “investment” they “could not be happier with” after a 14-hour drive where all their luggage stayed secure and dry through bad weather, noting they “didn’t even know it was back there.” Another user successfully took it on a grueling 4,900-mile road trip through rough terrain, but only after making a crucial modification: upgrading the standard folding pins to Grade 8 hardware for peace of mind, suggesting the stock bolts may be a weak point.
However, the negative feedback is equally strong and centers on two key areas: assembly and durability, particularly on RVs. One user detailed the “significant misalignment” of parts that required two people to force together. The most alarming feedback comes from RV owners. One reported that their carrier, loaded with less than 200 lbs, began “drooping on both sides” with failing welds after less than six months. Another on a Texas-to-Alaska trip saw their carrier start to bend with under 250 lbs on it before they even left the lower 48. This feedback paints a clear picture: it’s a capable carrier for cars and SUVs, but potentially hazardous when subjected to the unique physics of being attached to an RV.
How Does the Mockins XXL Carrier Compare to the Competition?
The Mockins XXL 70″x30″ Cargo Carrier w/ Waterproof Bag is a massive, all-in-one solution, but it’s not the only option on the market. Depending on your needs for weight, size, and vehicle type, one of its competitors might be a better fit.
1. MAXXHAUL 60″ Aluminum Cargo Carrier Rack
- Constructed from extruded aluminum material that is durable, light weight making it easy to install. Will not rust and is easy to clean and maintain
- Features a heavy duty steel under frame support that has a rugged powder coat finish and a 2" x 2" hitch shaft to fit standard Class III and IV hitch receivers
- Also include reflector strips and red-colored corners to provide extra visibility for added safety
The most significant difference with the MAXXHAUL carrier is its aluminum construction. This makes it substantially lighter than the steel Mockins model, a huge advantage for those who need to install and remove their carrier frequently by themselves. However, this comes at the cost of size; at 60″ x 22″, it offers significantly less surface area than the Mockins XXL. It shares the 500 lb capacity, but it’s a bare-bones rack. You’ll need to purchase a cargo bag, straps, and a hitch stabilizer separately. This is an excellent choice for someone who prioritizes low weight and ease of handling over maximum capacity and an all-inclusive kit.
2. CURT 18153 60×24-Inch Basket Cargo Carrier 500 lbs
- ENHANCED SECURITY. This trailer hitch cargo carrier keeps your items secure during travel, featuring 6-inch high walls around the cargo basket. These walls can be used to fasten a cargo net or cargo...
- ADAPTABLE. This cargo hitch carrier is equipped with a folding, angled shank. The folding feature allows the cargo carrier to be folded up when not in use, and the angled shank provides additional...
- EASY TO CLEAN. This hitch mounted cargo carrier frees up cargo space inside your vehicle and keeps messy items outside your vehicle. It also features a mesh base to easily clean up messes
CURT is one of the most respected names in the towing and hauling industry, and this carrier reflects their reputation for quality. Like the Mockins, it’s made of durable, powder-coated steel and features a convenient folding shank. Its dimensions (60″ x 24″) are generous, though still smaller than the Mockins XXL. The CURT 18153 is a direct competitor for users who want a reliable, strong steel carrier from a trusted brand but don’t necessarily need the gargantuan size or the full accessory bundle that Mockins provides. It’s a solid, dependable workhorse for those who may already own straps and other accessories.
3. ECOTRIC Roof Rack Cargo Basket with Cross Bars
- Application: The roof cargo basket fit for most vehicles with cross bars
- High-strength Structure: The roof cargo basket is made of steel, making sure this basket high strength and not easy to damage. Featuring black powder coated surface finish, making this basket against...
- Dimensions: The size of this roof cargo basket is 50-3/8 in(L) x 39in(W) x 4-5/8 in(H). It can carry a weight of 150 lbs
The ECOTRIC model represents a completely different approach to external storage. As a rooftop basket, it’s the ideal alternative for individuals who don’t have a trailer hitch, want to preserve full access to their vehicle’s rear liftgate at all times, or drive a smaller vehicle where a hitch carrier might be impractical. Its primary limitations are a much lower weight capacity (150 lbs) and the requirement that your vehicle already has roof rails. It’s designed for lighter, bulkier items like camping gear or luggage, not heavy-duty hauling. This is the go-to option if a hitch-mounted solution isn’t feasible for your vehicle.
Our Final Verdict: A Capacious Carrier with Some Important Caveats
After extensive hands-on testing and analysis of user feedback, our verdict on the Mockins XXL 70″x30″ Cargo Carrier w/ Waterproof Bag is clear: it is an absolute beast of a hauling solution with a few significant “ifs.” For large families with SUVs or vans who need to maximize their cargo space for road trips, this all-in-one kit is a phenomenal value. The massive platform, combined with the excellent waterproof bag and a full suite of necessary accessories, solves the packing puzzle in one purchase. When properly assembled and used on a suitable vehicle, it’s a road-trip game-changer.
However, that recommendation comes with strong caveats. You must be prepared for a potentially frustrating and physically demanding assembly process. More critically, based on overwhelming user reports, we cannot recommend this carrier for use on any RV or travel trailer due to the risk of structural failure. For its intended use on a standard car, truck, or SUV, it’s a capacious and feature-rich option, but we’d advise inspecting all welds upon arrival and considering an upgrade to the folding pins for ultimate long-haul security. If you fit the ideal user profile and are up for the initial setup, the Mockins XXL will serve you well.
