About Us

Rowland Diesel provides professional Master Certified Mechanic consultation services for legal professionals, fleet operators, commercial vehicle owners, and repair facilities requiring expert-level technical analysis and documentation. Our consulting services support litigation, regulatory compliance, fleet maintenance optimization, and advanced diagnostic troubleshooting for diesel and commercial motor vehicles.

In addition to advanced mechanical expertise, Rowland Diesel mechanics are experienced Class A CDL over-the-road drivers, with real-world operational experience in heavy-haul and hazardous materials (hazmat) transportation. This dual qualification provides a comprehensive perspective that integrates mechanical standards, operational practices, driver responsibilities, and DOT/FMCSA compliance requirements.

Consultations are conducted by a Master Certified Mechanic with extensive hands-on experience in diesel engine systems, drivetrain failures, electronic diagnostics, emissions systems, preventive maintenance programs, and post-repair verification. Services include objective technical evaluations, root-cause failure analysis, maintenance record review, compliance assessments, and expert guidance on complex mechanical, electrical, and operational issues.

For legal and insurance matters, Rowland Diesel offers expert witness–level consultation, including written technical opinions, affidavits, declarations, and case support for disputes involving vehicle failures, improper repairs, maintenance negligence, operational errors, warranty claims, and DOT/FMCSA compliance matters. All findings are documented using industry-accepted standards and terminology suitable for court, arbitration, or regulatory review.

Fleet-focused consulting services assist commercial operators with maintenance program development, compliance evaluations, diagnostic strategy, cost control, and equipment reliability improvement, particularly for heavy-duty, heavy-haul, and hazmat-regulated operations.

Rowland Diesel delivers independent, professional, and defensible technical expertise, combining mechanical authority with real-world Class A CDL operating experience to support legal, fleet, and commercial clients.
