The sophistication of the modern diesel tractor/truck has made it difficult for owner operators and even some in-house fleet technicians to manage. The number one tool against failures and breakdowns remains a stringent preventive maintenance program. A reactionary approach to truck issues, be it engine or drive line, is the most expensive and frustrating approach. At TDI we work closely with our customers and utilize the power of Fullbay and their custom portal, scheduling and keeping records of all preventive maintenance done on their entire fleet.
