The Mobile-Service Advantage

Move the Service—Not the Entire Fleet.

Sending vehicles to a repair facility consumes more than shop time. Employees must transport vehicles, arrange return transportation, coordinate keys, adjust operating schedules, and monitor work across multiple locations. Mobile fleet service brings eligible work directly to the vehicles, allowing maintenance to be coordinated around the operation rather than forcing the operation to work around the shop.

Reduce Vehicle Movement

Limit unnecessary trips between the fleet's operating location and an outside repair facility.

Consolidate Maintenance

Complete eligible work across several vehicles during one coordinated service visit.

Protect Productive Time

Reduce employee time consumed by transporting vehicles and waiting for service.

Improve Fleet Visibility

Identify open defects, maintenance requirements, and shop-level repairs while the technician is already on-site.

Mobile Service Capabilities

Practical Service Delivered at Your Facility.

Mobile-service eligibility depends on the vehicle, requested work, site conditions, required equipment, parts availability, and operating market.

Mobile-service eligibility is confirmed before scheduling based on the vehicle, requested work, site conditions, parts, required equipment, and market.
