Mobile truck repair questions, answered
Do you offer 24/7 roadside truck repair in Charleston, SC?
Yes. Fleet Doc runs 24/7 mobile and roadside service for diesel trucks, box trucks and fleets across Charleston, North Charleston, Summerville, Mount Pleasant, Goose Creek and the surrounding counties, including the I-26 and I-95 corridor. Call (854) 205-1972 any time.
What areas does Fleet Doc serve?
We are based in Charleston, SC and cover Charleston, Berkeley, Dorchester and Orangeburg counties, with service across the Carolinas for fleet accounts. We come to your yard, jobsite, or the roadside.
What types of trucks do you work on?
Medium and heavy-duty diesel trucks โ box trucks and straight trucks, tractors and semis, trailers, dump trucks and work trucks โ plus the liftgates, roll-up doors and reefer units that come with them.
Can you do DOT inspections at our yard?
Yes. We perform annual DOT inspections and brake inspections on-site with fleet pricing, and we supply the paperwork and per-vehicle records your fleet needs to stay compliant.
Do you repair liftgates and roll-up doors on box trucks?
Yes โ liftgate service and roll-up door repair are specialties most shops will not touch on-site. We fix them where the truck sits.
Is mobile truck repair more expensive than taking it to a shop?
Usually it is cheaper once you count the tow and the lost days. A service call fee covers the trip within 25 miles; after that you pay for the work, not for the truck sitting in a shop queue.
Do you offer fleet maintenance programs?
Yes. We set up preventive-maintenance schedules, priority scheduling and per-vehicle service history for fleets of any size, from a couple of box trucks to a full yard.
How do I request mobile truck repair?
Call or text (854) 205-1972, or use the Request Service form on our contact page with your truck details and location. Roadside calls are answered 24/7.
Broke down or due for service?
