Does the RAMBox make the bed smaller?

In short, the RAMBox does not shorten the bed’s overall length. It adds integrated, weatherproof storage along the bed sides, which slightly reduces the usable width of the bed near the walls but leaves the central cargo floor intact for most loads.


What is the RAMBox?


The RAMBox Cargo Management System is a pair of lockable, weatherproof storage bins built into the bed sides of certain Ram pickup trucks. The boxes sit behind the rear wheel wells and run along each side of the bed, providing secure storage without encroaching on the cab space. The RAMBox is designed to integrate with the truck’s rails and drainage and is available on many RAM 1500, 2500, and 3500 configurations as an option or Mopar accessory.


Location and design


Placed along the bed’s sides, RAMBox adds storage volume that sits above the floor and behind the wheel wells. The lids open upward, and the boxes are weather-sealed and lockable to protect contents from rain and theft.


Impact on bed size and cargo space


To understand whether the RAMBox makes the bed smaller, note that the bed length remains the same; the changes occur in how the side space is used. RAMBox occupies part of the bed's side area, which reduces the amount of floor space immediately next to each side rail. The central portion of the bed floor—the main cargo zone—remains fully usable for long items, crates, or bulk cargo.


Before listing the key points, here's a quick outline of what the RAMBox changes and does not change:



  • It does not shorten the bed length from tailgate to cab.

  • It adds two weatherproof storage compartments along the bed sides, behind the wheel wells.

  • It reduces the immediate side-floor area near the rails, which can affect placing items flush against the bed wall.

  • It does not limit the central cargo floor in the middle of the bed.

  • It requires a RAMBox-equipped bed and may be offered as a factory option or Mopar accessory depending on model and year.


Concluding: For most users, the RAMBox provides additional organized storage without materially constraining the bed's primary cargo area. The trade-off is less side-floor width near the rails, which is usually acceptable for users who value secure, weatherproof storage.


Practical considerations


When deciding whether RAMBox is right for you, consider how you typically load the bed, the items you carry, and whether the side-storage boxes fit your gear dimensionally. The RAMBox system is designed to work with most cargo in the center of the bed, while the sides offer closed storage for tools, recovery gear, and small parts.



  • Not all RAM configurations include RAMBox; check compatibility with your truck’s year, trim, and bed length.

  • RAMBox adds weight and changes the bed’s side storage layout, which can affect loading of items that would otherwise sit directly against the bed walls.

  • Security is improved due to lockable lids, but you should still secure items inside RAMBox as needed.


Conclusion: If you need extra secure storage and don’t rely on every inch of side-bed floor space, RAMBox is a practical option that does not reduce the bed’s essential length or the central cargo area.


Summary


The RAMBox does not shrink the bed length. It adds side storage compartments along the bed, which reduces some side-floor space near the rails but preserves the central cargo area. It is most valuable for organization and security rather than for increasing raw cargo capacity, and availability depends on model/year and bed configuration.

Does the RAM box make the bed smaller?


The ram box takes up the entire left and right sides of the bed. It's a lot narrower compared to a bed without it.



How big is the bed in the RamBox?


RamBox dimensions vary by the truck bed length, with the 6'4" bed featuring an 8.6 cubic foot storage system and the 5'7" bed offering 7.3 cubic feet. The RamBox is integrated into the truck bed's side rails, providing lockable, weather-sealed storage space on both sides of the bed.
 

  • 6'4" bed with RamBox:
    • Storage: 8.6 cubic feet of storage across both sides. 
    • Bed length: 76.3 inches. 
  • 5'7" bed with RamBox:
    • Storage: 7.3 cubic feet of storage across both sides. 
    • Bed length: 68.5 inches (calculated from total length). 



What are the pros and cons of RAM box?


Pros are they're super handy and convenient, and they lock. They get a ton of use. Cons, it reduces options for bed racks and toppers. There are some toppers that work with them, but not a lot.



What are the benefits of using RamBox?


Rambox workspaces can be a helpful tool for anyone who wants to implement the time blocking method effectively, as they allow you to organize and prioritize your communication tasks based on their level of importance.
