Newer fuel and service trailer models are built to add a rear utility box at any time. We've gone so far to pre-drill holes in the frame to adjust the position of the axles and ensure proper weight distribution. The utility box measures 35.5'"d x 58.5"w x 47"h and provides ample space for additional service-minded options.
This option can be field-installed on FST Series, Multi-Tank and similar trailer models notable by a front enclosure with hatch-style doors. It cannot be added to older trailers with front doors that open to the side, such as ADT Trailers.
