Everything you need to handle diesel and DEF is consolidated in this sleek toolbox. It includes a 100 gallon diesel fuel tank, 18 gallon DEF tank and pumps for both systems. A heating option is available.
It's designed to fit between the cab and wheel wells and leave enough room for gooseneck and fifth wheel hitches. It houses everything from the fill port to the dispensing nozzle so nothing protrudes from the structure.
