If you want a secure, hitch-mounted solution for motorcycles and gear that stays dry in any storm, choose Forluck Waterproof Hitch Mount; if you need maximum rooftop capacity for family road trips on vehicles without racks, choose HubPax 16.
• Forluck Waterproof Hitch Mount: Its biggest strength is the heavy-duty PVC construction with eight reinforced straps designed specifically for hitch baskets, while its trade-off is that it requires a standard steel hitch receiver to function. This pick is for riders securing motorcycle gear or travelers needing a rigid, wobble-free mount behind their truck or SUV.
• HubPax 16: Its biggest strength is the versatile design that fits vehicles with or without roof racks using anti-slip mats and door hooks, while its trade-off is that it sits higher on the roof line and relies on friction-based stability rather than a fixed metal frame. This pick is for families loading suitcases and tents onto sedans, minivans, or cars lacking factory crossbars.
The Forluck Waterproof Hitch Mount Cargo Carrier Bag is engineered for those who prioritize stability and protection over raw volume. At 15 cubic feet with dimensions of 58 inches by 19 inches by 24 inches, this soft-shell bag offers a substantial amount of storage space that feels more compact and lower to the ground than typical rooftop alternatives. The design focuses heavily on keeping your load secure against the forces of highway driving. It features eight heavy-duty reinforced straps equipped with durable buckles, which are critical for preventing movement and vibration. Whether you are navigating rough terrain on an off-road adventure or cruising down the interstate, these straps ensure the bag remains tight and stable against the cargo carrier basket.
The material choice here is deliberate and functional. Constructed from premium soft-shell PVC, this bag is fully waterproof, offering resistance against rain, snow, dust, and road debris. This level of protection is essential when carrying expensive motorcycle helmets, riding jackets, or sensitive camping equipment. Unlike some fabric carriers that might leak under heavy pressure, the PVC shell creates a robust barrier. Additionally, the inclusion of a combination lock adds a layer of security, ensuring your belongings stay safe even when you stop for a break. The package also includes a convenient storage bag, allowing you to fold the unit down compactly when not in use, which saves valuable garage or trunk space.
This product is ideal for owners of trucks, SUVs, pickups, and RVs who already have a standard hitch-mounted cargo basket. If you are planning a motorcycle trip where you need to strap gear to a rear rack, this bag fits perfectly into that ecosystem. It is not designed to sit on a flat roof without rails; it needs the structure of a hitch carrier to anchor those eight straps effectively. However, for anyone with the right vehicle setup, it provides a reliable, weatherproof solution that keeps your cargo low and centered, minimizing wind drag compared to high-profile rooftop bags. You should skip this option if you drive a sedan without a hitch or if you need to transport items taller than the bag's height allows.

The HubPax 16 Car Rooftop Cargo Carrier Bag is built for versatility and ease of access on almost any vehicle type. With a generous 16 cubic feet of capacity, it offers slightly more internal volume than the hitch-mounted alternative, making it a perfect solution for family road trips where you need to pack tents, sleeping bags, and multiple suitcases. The standout feature of this design is its ability to fit all vehicles, regardless of whether they come equipped with roof racks, side rails, or crossbars. This flexibility eliminates the need for permanent modifications or purchasing additional hardware before you can start loading up your car.
Weather protection is central to the HubPax 16 experience. It is crafted from 100% waterproof nylon featuring heat-welded seams and strong weatherproof zippers. These details ensure that your gear stays completely dry through heavy rain, snow, wind, and sand. The design accounts for the harsh realities of long-distance travel, sealing out moisture better than many competitors. To make installation as simple as possible, the kit includes an anti-slip mat that stabilizes the load and protects your car roof from scratches. It also comes with six door hooks, which allow you to secure the bag safely to the vehicle doors, adding an extra layer of restraint beyond just the straps.
Setup is incredibly fast, taking only minutes to get on the road. You simply place the mat and bag on the roof, load your luggage, zip it up, and tighten the straps. The package contents are comprehensive, including a security lock to prevent zipper heads from sliding while driving and to deter theft. The black and orange color scheme makes it highly visible, adding a safety element during low-light conditions. This product is best for drivers of sedans, minivans, and smaller SUVs who lack factory roof rails but still need extra cargo space. It is less suitable for those who prefer a lower center of gravity or who plan to mount the bag on a specific hitch-mounted frame, as it is designed specifically for the roof surface.
• Best for Motorcycle Gear & Rear Storage → Forluck Waterproof Hitch Mount: Its lower profile and hitch-specific mounting system make it safer for transporting heavy, bulky motorcycle accessories without interfering with rear visibility.
• Best for Vehicles Without Roof Racks → HubPax 16: The inclusion of door hooks and an anti-slip mat allows it to attach securely to flat roofs where no rails exist, a capability the Forluck lacks entirely.
• Best for Maximum Volume → HubPax 16: At 16 cubic feet versus 15 cubic feet, the HubPax offers slightly more room for large items like family luggage sets or oversized camping gear.
• Best for Stability on Rough Terrain → Forluck Waterproof Hitch Mount: The eight reinforced straps and rigid attachment to a steel basket reduce wobble significantly more than a bag resting on a car roof.
• Best for Quick Setup on Any Car → HubPax 16: You can throw it on the roof in minutes without needing to locate a hitch receiver or install a separate carrier basket first.
• Best Material Durability → Forluck Waterproof Hitch Mount: The heavy-duty PVC shell is generally more resistant to abrasion from road debris and potential snagging than standard nylon roofing materials.
• Best for Weather Sealing Features → HubPax 16: The combination of heat-welded seams and dedicated weatherproof zippers offers a sealed environment specifically tested for extreme exposure.
• Best for Low Wind Drag → Forluck Waterproof Hitch Mount: Being mounted lower on the vehicle reduces aerodynamic interference, whereas the rooftop position of the HubPax increases wind resistance slightly.
After analyzing the specifications and intended use cases for both products, I would choose the Forluck Waterproof Hitch Mount if my primary goal was transporting motorcycle gear. The reason is simple: the lower center of gravity and the rigid connection to a hitch basket provide a level of security and stability that a rooftop bag cannot match. When carrying heavy motorcycle helmets or bulky riding jackets, having the load anchored directly to the rear frame of the vehicle prevents dangerous sway and keeps the weight distribution optimal. While the HubPax 16 is an excellent solution for general family travel on sedans, the Forluck's specialized design for hitch mounts makes it the superior choice for serious riders who need a dependable, weather-tight home for their gear behind the vehicle.
No, the Forluck Waterproof Hitch Mount is designed specifically to attach to standard steel hitch cargo baskets or roof racks on trucks, SUVs, and RVs; it does not include the anti-slip mats or door hooks needed for a flat roof.
No, the HubPax 16 fits all vehicles with or without racks, utilizing an included anti-slip mat and six door hooks to secure the bag to the roof or side rails.
Both bags offer 100% waterproof protection, but the Forluck uses a heavy-duty PVC shell while the HubPax relies on heat-welded nylon seams and weatherproof zippers to keep gear dry in rain and snow.
The Forluck includes a built-in combination lock for added security, while the HubPax 16 comes with a security lock to prevent zipper heads from sliding and protect the luggage during transit.
