A broken-down truck doesn’t make money. Hauling it to a shop and waiting for an open bay can turn a one-hour repair into a lost week. Jonathan’s Fleet Service brings the tools, the parts and the know-how to wherever your truck is sitting — the highway shoulder, your yard, a lease road or a job site — and fixes it there whenever it can be done safely on site.
