Hitch Cargo Carrier Bag 16 Cu.Ft. Gray - Waterproof Truck Storage

In this review the Mockins 16 cu.ft. gray hitch cargo carrier bag is evaluated for road trips, weekend hauls, and seasonal moves; the bottom line is simple: it is a practical, weather-ready solution for anyone who needs reliable extra exterior storage. Sized at 58'in x 20'in x 24'in, the bag delivers generous capacity for suitcases, backpacks, camping gear and bulky items that do not fit inside the cabin. The overall construction and waterproof detailing are the single biggest reasons to buy, because they keep gear dry and protected while mounted on a hitch basket or used in a truck bed.

Key Features

• Spacious storage: The 16 cu.ft. interior holds multiple suitcases, sleeping bags and tents so you can free up interior space for passengers.
• All-weather material: Heavy-duty abrasion-resistant vinyl withstands road wear and helps the bag tolerate rain and wet conditions on long drives.
• Waterproof closure: Zippers are covered by a 2'in flap with Velcro to reduce water intrusion and protect contents in poor weather.
• Included security and straps: The kit ships with six buckle straps and a combination lock to secure the bag to a hitch carrier and deter opportunistic theft.
• Easy handling: Wrap-around zippers and side handles make loading and lifting the bag straightforward, while it folds down into the included carry case when not in use.
• Durable seams: Reinforced seams resist tearing so the bag stands up to repeated loading and highway vibration.

Who It's For

This bag is a good fit for drivers who use a hitch-mounted cargo basket or need extra covered storage in a truck bed for camping, moving equipment or weekend travel. Its size and waterproofing suit families, outdoor enthusiasts and vendors hauling bulky supplies that do not require rigid protection.

Those who need a rigid hard-shell carrier, precise lock systems for high-value items, or products sized for very small crossbars should look elsewhere; this is a soft-shell, flexible storage solution that prioritizes weather protection and volume over armor-like security.

Pros & Cons

Pros

• Material quality and waterproofing perform well to keep items dry in rain.
• Large 16 cu.ft. capacity fits multiple suitcases and bulky gear with room to spare.
• Includes straps and a combination lock for basic security and straightforward installation.

Cons

• Strap quality gets mixed feedback and may require reinforcement for very heavy or shifting loads.

Specifications
