Mockins 15 cu ft Trailer Hitch Cargo Carrier Bag with 4 Packing Cubes — Weatherproof, Heavy-Duty 48"×18"×31"

The Mockins 15 cu ft Trailer Hitch Cargo Carrier Bag with four packing cubes is a weatherproof, heavy-duty hitch-mount storage solution that organizes and protects road-trip gear on your trailer or truck bed.

Whether you tow a cargo basket or need extra storage behind a car or SUV, this Mockins bundle converts a hitch into a secure, high-capacity luggage compartment. Built from abrasion-resistant vinyl with reinforced welded seams and protective zipper flaps, the bag resists rain and road spray while the included packing cubes make loading and unpacking fast and tidy. Two heavy-duty buckle straps and a combination lock add retention and basic theft deterrence, while the fold-flat design keeps it compact when not in use.

How much gear does this hitch carrier actually hold?

This cargo bag provides 15 cubic feet of internal space in a 48" x 18" x 31" envelope, enough for multiple suitcases, a tent, sleeping bags, or bulky camping supplies. The four packing cubes subdivide that volume into organized stacks so nothing shifts during transit.

• Overall dimensions: 48" x 18" x 31" (15 cu ft)
• Four packing cubes, each 22" x 15" x 15"
• Packing cube weight capacity: up to 90 lb each
• Fits standard 2" hitch-mounted baskets and most rear cargo racks

What keeps my gear dry and protected on wet roads?

Mockins uses abrasion-resistant vinyl and welded seams to form a rugged outer shell that resists punctures and wear. The main zipper sits under a Velcro-secured flap and the zippers are water-resistant to limit moisture entry from rain or splashes.

• Durable vinyl construction for abrasion and water resistance
• Welded seams for stronger seam integrity
• Protected waterproof-style zippers beneath a Velcro flap
• Combination lock compatible zipper sliders for added security

How does the included packing cube system improve organization?

Instead of one large loose cavity, the four soft packing cubes let you pre-pack clothing, gear, or tools, then stack them neatly inside the carrier. Double zippers on each cube speed access and make rearranging items simple at campsites or rest stops.

• Four soft-sided cubes for grouping items by type or person
• Double zippers for quick opening and re-sealing
• Cubes can be used independently in trunks or truck beds
• Each cube rated to support up to 90 lb for sturdy stacking

Is the bag stable on the road and easy to attach?

The Mockins hitch cargo bag includes two heavy-duty buckle straps to anchor the unit to your hitch basket or carrier. The straps limit movement on uneven roads, while the bag’s compact footprint keeps rear visibility reasonable compared with larger rooftop or trailer setups.

• Includes two heavy-duty buckles and adjustable straps
• Low-profile footprint reduces wind drag and sway
• Folds flat for storage when not in use
• Combination lock provides added peace of mind while parked

Who is this for? The Mockins 15 Cu Ft Trailer Hitch Cargo Carrier Bag with 4 Packing Cubes suits travelers, campers, and small families who need waterproof, organized storage outside the cabin. It’s a practical choice when trunk space is full, when you want quick access without roof racks, or when you need an affordable, foldable hitch-storage option for weekend getaways and longer road trips.
