| Aspect | Per Diem Owner Operator Reefer | Per Diem Owner Operator Dry Van |
|---|
| Type of Trailer | Refrigerated (Reefer) | Dry Van |
| Required Certifications | Commercial Driver's License (CDL), Reefer endorsement | CDL, possibly a dry van endorsement |
| Work Environment | Cold storage, temperature-controlled loads | Standard freight, no temperature control |
| Industry Usage | Food, pharmaceuticals, perishable goods | General freight, non-perishable goods |
Both roles involve operating a truck as an owner-operator with per diem pay, but Reefer drivers handle temperature-sensitive loads requiring refrigeration, while Dry Van drivers transport non-perishable freight. The main differences are the trailer type, required endorsements, and the nature of the cargo.
