Jonathan's Fleet Service
About Jonathan Your mechanic, on call.
Jonathan Danysh keeps South Texas trucks working — wherever they break down, whenever it happens.
Jonathan Danysh runs Jonathan’s Fleet Service for one reason: when your truck stops, you need someone who doesn’t. From ranch roads and oil fields to highways and job sites, he provides dependable mobile diesel repair throughout South Texas.
We understand the demands of working trucks because we live and work here too. Breakdowns don’t wait for business hours, and neither do we. When your equipment needs attention, we’re just a phone call away, day or night.
What customers notice
Fast response
Same-day, often within the hour — even late at night when other services won’t pick up.
Fair prices
Customers mention reasonable, affordable pricing again and again in their reviews.
Honest advice
He tells you what the truck needs — and doesn’t sell you what it doesn’t.
Above and beyond
From custom welds out of a single gasket to getting stranded drivers home safe.
“Amazing customer service! Jonathan came out the same day and went above and beyond what you’d expect from a mechanic. He gave us a fair price and didn’t offer anything we didn’t need.” — DLC, Google review
More than repairs
Besides roadside and fleet repair, Jonathan’s Fleet Service offers federal DOT inspections, pre-purchase inspections, fleet subcontracting and pilot/escort services for oversized loads — so one call covers a lot of what a working truck needs.
Broken down? Day or night
When you're stuck, we're one call away.
Tell us what the truck is doing and where it is. Jonathan picks up 24 hours a day and rolls out to you.
