Some detail pics and marketing from the company that makes them. Save you the trouble of looking it up. Somewhere in there: It's a no for RamBox
Because of AeroBox's unique design, it can do things that most other truck boxes cannot
Rear mounting allows for easy access to cargo without the need to climb into the bed
Can be easily removed and rolled away to provide you with all of your truck bed area when needed
Sits below rails which allows for use with most traditional tonneau covers
Puts weight over rear wheels for increased traction
Patented design Improves truck's aerodynamics
AeroBox increases your fuel economy by reducing your truck's wind drag. The unique position and computer engineered shape of the AeroBox™ provides significant aerodynamic improvement, increasing fuel economy. According to CFD analysis of a truck with the tailgate up as opposed to a truck with an AeroBox, it was found that AeroBox reduces the drag coefficient by 4.25%. ProPickup Magazine 03/2012 article on truck aerodynamics (
http://www.propickupmag.com/tailgate-down-myth/) indicates that, "such a reduction in the pickup’s drag could be translated to the equivalent of a free gallon of gas for every 20-gallons burned.
The AeroBox™ is a rear mounted, secure truck cargo box that improves aerodynamics and creates an easily accessible and portable space for storage. This unique tailgate cargo box integrates practical, well-designed features such as tie down hooks, easy access to cargo at tailgate, configurable storage, and much more, to make your work easier and your truck more useful for you and your family. AeroBox™ also works terrific with hitch cargo racks on SUV's, vans, and cars.
GET ORGANIZED
Avoid the hassle of trying to retrieve loose items that have rolled around in the truck bed. Keep items secure from damage and out of sight of thieves. You don't have to stuff your valuables in the cab anymore because you don't have a good way to store them in all that space you have in the bed! The AeroBox rear mounted cargo box will greatly increase the ways you can use your truck by providing easy to access, secure storage space at the tailgate.
ADD UTILITY
The unique rear mounted truck bed position of the AeroBox™ provides many advantages over traditional tool/cargo boxes mounted behind the cab. See how much more use you can get from your truck when your stored items are more easily accessible at the tailgate! The Aerobox is also portable and can be easily "un-docked" from the truck to open up the full cargo capacity of your bed, wheeled away to your job-site, campsite, or nicely stored in the garage. Try that with a traditional truck bed tool/cargo box! The AeroBox can also be used with many tonneau covers (please confirm fit before buying).
