Along with the RamBox, you get a ton of storage space on the inside, which should be enough for many:
The 2014 Ram 1500 takes care of you and everything you haul. The rear under-seat storage and available fold-flat load floor in the Ram 1500 Crew Cab and Quad Cab models keeps everything organized whether it’s the tools of the trade, sports equipment or things just better left out of sight. In addition, the space behind the front seat of Ram 1500 Regular Cab is so large you can stash three industrial-sized 18.9 L containers back there. The Crew Cab also offers Class-Exclusive in-floor storage3. So go ahead and haul whatever you want.
