This DROM box, aka a Dromedary Box, is the type used behind the cab of a semi truck to add additional cargo space. This particular one is 57" front to back, 96" in width and 82" high. I also offer a 96" front to back version, as well as both in 104" height. It is designed to hold two pallets of palletized cargo. It has passed the software checks, but should there be an issue or question, contact me via the designer link or direclty via email to modelmechanic@gmail.com
