Refrigerated carriers continue to lose significant revenue at cold storage facilities that require lengthy inbound pulp temperature verification. A typical frozen food or produce receiver may hold a reefer trailer at the dock for 8 to 14 hours while quality control teams perform slow, manual pulp checks. During this time the trailer’s auxiliary diesel engine runs continuously, consuming $18 to $28 per hour in fuel with no corresponding detention payment from the facility or the broker.
Traditional paper guard gate passes and verbal check-in logs are routinely disputed during the 210 EDI process. Without precise, tamper-proof timestamps and telemetry, motor carriers cannot prove when the trailer arrived, when pulping began, or how many hours the reefer unit idled at the dock. The result is thousands of dollars in unrecoverable detention and fuel per month for even modest reefer fleets.
The Cold Storage Holdover Ambush
Cold storage warehouses frequently cite food-safety protocols that require pulp temperatures between -10 °F and 34 °F before product can be accepted. While the carrier may arrive with a properly pre-cooled load, the receiver’s QC team often works sequentially across multiple trailers. The driver is forced to remain on-site, the reefer unit burns diesel, and the carrier’s clock keeps running. When the load is finally accepted, the broker’s TMS often shows only “live unload” with no supporting evidence of the extended dwell. The carrier’s driver settlement and fuel surcharge calculations suffer accordingly.
The Strong Tower ColdAudit Architecture™
Exspeedite CheckPoint delivers an automated, sensor-integrated solution that captures every critical timestamp and telemetry point without requiring the driver to perform extra steps. The architecture works with existing Truckmate, McLeod, and TMW systems through standard EDI 214 status updates and SQL-based integration points.
- Geofenced cold dock arrival and pulping timestamp: When the tractor crosses the facility geofence, CheckPoint automatically records the exact minute the reefer unit reports to the receiver. The system logs the trailer’s microprocessor data confirming pre-cool compliance (-10 °F to 34 °F) and stores the pulp temperature reading alongside the arrival timestamp.
- Microprocessor engine hour and fuel burn correlation: CheckPoint pulls auxiliary engine hours and fuel consumption directly from the reefer unit’s telemetry. It cross-references these values against the documented dock dwell time to calculate precise auxiliary fuel burn. The platform then automatically generates an additional fuel surcharge recovery line item that can be appended to the detention invoice sent via EDI 210.
- Certified receiver dwell dossiers: With one click, dispatch can export a certified PDF dossier containing geofence arrival proof, pulp temperature verification, continuous reefer telemetry, and total dock-door detention hours. These dossiers are formatted for immediate upload to the broker’s TMS or for driver settlement support.

Ending Frozen Freight Exploitation
By combining geofencing, reefer microprocessor telemetry, and automated PDF dossier generation, Strong Tower CheckPoint gives refrigerated carriers the engineering-grade evidence needed to collect full detention and auxiliary fuel reimbursement. The system integrates cleanly with existing EDI 204/214/210 workflows and requires no changes to driver settlement processes in Truckmate, McLeod, or TMW. Carriers simply receive cleaner data that survives broker audits and improves both cash flow and driver pay accuracy.
Independent by design. Strong Tower Consulting, LLC and Exspeedite LLC are separately organized sister companies under common ownership (founded 2008 in Minnesota by Scott Elliott). Carriers are never required to buy our software. Many fleets choose to use CheckPoint solely for its automated audit and billing support while continuing to run their preferred TMS.

Frequently Asked Questions
Yes. The platform pulls microprocessor data at the moment the tractor enters the geofence. It records the supply air, return air, and pulp probe temperatures, storing them with a tamper-proof timestamp. This evidence is included in the certified PDF dossier and can be attached to any dispute involving pre-cool compliance.
CheckPoint continues to monitor the trailer via its integrated telematics link even after the tractor is detached. When the trailer is later spotted to a dock door, the system correlates the earlier arrival timestamp with the subsequent pulping event. The resulting dwell calculation includes all uncompensated time the reefer unit was running, whether the tractor was attached or not.
The system uses actual microprocessor-reported fuel burn data rather than estimates. It factors in real-time engine hours, ambient temperature readings from the reefer unit, and the precise duration of dock holdover. This produces an accurate, auditable auxiliary fuel surcharge that can be added to the 210 EDI invoice or used in driver fuel settlement calculations.
Yes. CheckPoint was built for seamless integration with Truckmate, McLeod, and TMW environments. It ingests EDI 214 status messages, writes detention and fuel line items back into the load record, and exports SQL-compatible datasets for custom reporting or driver settlement adjustments.
Motor carriers operating refrigerated fleets should no longer accept uncompensated 8-hour dock holdovers as the cost of doing business with cold storage receivers. The combination of precise geofencing, pulp temperature verification, and auxiliary fuel telemetry now makes every hour of detention and every gallon of reefer fuel recoverable.
