MARKSIGN Truck Bed Cargo Bag 26 cu ft Waterproof Heavy-Duty 51x40x22 with Built-In Ratchet Tie-Downs

MARKSIGN's 26 cubic foot truck bed cargo bag is a heavy-duty, fully waterproof storage solution that keeps luggage, gear, and supplies protected on any pickup truck.

This oversized, welded cargo bag measures 51" x 40" x 22" and is engineered to free up interior space while securing belongings for road trips, moving days, or outdoor adventures. Constructed with welded seams, a vinyl-coated #10 zipper, and a Velcro rain flap, the bag resists rain, snow, UV exposure, tears, and abrasions. Integrated ratchet-style tie-down straps and reinforced handles make it simple to fasten and remove, and the included storage sack keeps the bag compact when not in use.

How much gear can this cargo bag hold?

The MARKSIGN cargo bag offers 26 cubic feet of internal volume—large enough to carry several suitcases, camping equipment, or family luggage for a long trip. Its rectangular footprint and tall sidewalls maximize usable space and make packing straightforward.

• Dimensions: 51" x 40" x 22" (130 x 100 x 55 cm).
• 26 cubic feet capacity—fits luggage for 4–6 people depending on packing style.
• Wide opening and structured sides speed up loading and unloading.

Will this bag protect my items from rain and sun?

The bag is fully welded so there are no stitched holes to leak, and the fabric is treated for UV resistance. A vinyl-coated heavy-duty zipper combined with a Velcro-secured rain flap creates a water-shedding closure that keeps moisture, dust, and sunlight away from your cargo.

• 100% welded construction eliminates needle-holes that cause leaks.
• #10 vinyl-coated zipper plus Velcro rain cover for extra protection.
• UV-resistant, tear- and scratch-resistant outer material for longevity.

How does it attach to different pickup trucks?

MARKSIGN built four integrated ratchet-style tie-down straps into the bag so you can anchor it to most truck bed anchor points without needing separate ropes. When not in use, straps tuck under Velcro shields at each corner to keep them tidy and out of the way.

• Four built-in ratchet tie-down straps compatible with standard bed anchors.
• Corner Velcro shields store straps neatly when not needed.
• Heavy-duty side handles let two people lift the bag in and out of the bed.

Will this fit my pickup model and how easy is it to store?

The bag’s dimensions are chosen to fit compact through full-size pickup beds, including popular models from Ford, Chevy, Ram, and Toyota. After use the cargo bag folds into the supplied storage pouch for compact, shelf-friendly storage at home.

• Universal fit for compact, mid-size, and full-size pickups (e.g., F-150, Silverado, Ram 1500, Tundra, Tacoma, Ranger).
• Two reinforced handles on each side for carrying and positioning.
• Included storage bag keeps it compact when not in use.

Who is this for: The MARKSIGN 26 cu ft truck bed cargo bag is aimed at drivers who need weatherproof, high-capacity storage outside the cabin—families taking road trips, outdoor enthusiasts hauling equipment, or anyone moving bulky items who wants a simple, secure solution. If you want to reclaim interior passenger space and keep gear protected on highways and backroads alike, this bag is designed to meet that need without complicated installation.
