Mobile Diesel Medic, Inc.

Mobile Diesel Medic, Inc. is a mobile heavy duty equipment and truck repair shop on wheels, based in Raleigh, North Carolina, that also takes on RV and bus repair. It comes to you, at a campground, storage lot or driveway, rather than asking you to haul a rig anywhere.

It works on RV motorhomes, toy haulers, tour buses, fifth wheelers, Coleman pop-up trailers, Airstreams, horse trailers, gasoline school buses, diesel pushers and double decker buses. The work covers air conditioning recharge and diagnostics, battery, alternator and starter troubleshooting, the full range of brake systems from air brakes to Bendix and Haldex components, check engine light and ECM diagnostics, DPF cleanout and regen, steering and suspension work, and the inverter, converter, generator, solar panel and shore power wiring that keeps the coach side of a rig running. It covers Raleigh, Durham, Chapel Hill, Garner, Cary and Apex.

No trip fee or hourly rate is published, so ask about both when you call. The business does say how it bills, in its own words: "We are not a flat rate shop, but bill actual hours." That distinction matters on a diesel chassis repair, where a flat-rate book time can reward a tech for rushing rather than getting it right.

Mark Armstrong runs the operation. Google rates it 4.6 stars from 41 reviews.

This is a good fit for an owner of a diesel pusher, converted bus or other diesel-chassis rig in the Research Triangle dealing with a brake, electrical, air conditioning or DPF problem, who would rather have a tech come to the rig than wait on a flat-rate shop.
