    “We would not hesitate to recommend DEI Truck & Fleet for all fleet equipment needs.”
    DEI Truck & Fleet is a skilled, efficient and well run fleet repair and maintenance facility. As commercial Beekeepers and Honey Packers, on-highway as well as off-highway equipment service and reliability are paramount. Equipment downtime is critical and DEI Truck & Fleet makes every effort to minimize it. Whether it is routine maintenance or emergency repair, Randy and his staff are quick to respond to ensure minimal downtime and loss of equipment serviceability. Beekeeping puts trucks and equipment in remote places at odd hours, 7 days a week. If and when a breakdown does occur, DEI Truck & Fleet will not only makes the repair, but if necessary, will also facilitate tow services from the field to their shop. This is extremely helpful in keeping the business moving forward and concentrating on our operational needs. DEI Truck & Fleet is a full service shop that provides service, maintenance and repair as well as CHP Safety BIT Inspections. As satisfied customers, we would not hesitate to recommend DEI Truck & Fleet for all fleet equipment needs.

    Great work and quick service! As the fleet manager for Cleansweep environmental I would like to say that Randy and his team always go out of their way to get our trucks back up and running as quick as possible.
