Mobile heavy-duty repair for 18-wheelers, trucks and trailers — anywhere in the Rio Grande Valley, any hour. A live person answers, a fully equipped truck rolls, and your driver gets moving again.
Call at 3 a.m. on a Sunday and a person picks up. You get a real ETA for your mile marker before we roll — not a callback promise.
Based in Pharr, running the freight corridors daily. Pharr, McAllen, Edinburg, Brownsville, Harlingen, Port Isabel and the long stretch up to Falfurrias.
EFS, Comdata Comchek, T-Chek, cards and Zelle. Your dispatcher can authorize a code by phone while the technician is still working — nobody hunts for an ATM.
Everything below happens where your truck sits — the shoulder, the yard, the truck stop, the customer's dock.
Immediate dispatch for breakdowns — jump starts, air leaks, and getting a dead rig off the shoulder safely.
Roadside details →Blowout on 281? Mobile patching, replacement and air delivery in commercial sizes, steer through trailer position.
Tire details →Brakes, suspension, drive lines and A/C — the repairs that normally mean a tow, done where the truck already is.
Repair details →Fleet PMs, oil and filter service, and DOT inspection prep — at your yard or the truck stop, on your schedule.
PM details →Doors, lighting and wiring, air lines, landing gear, kingpin and suspension — half the breakdowns in this Valley are the trailer, not the tractor.
Details →Air leaks, chambers, slack adjusters and lines. If it will not hold air it will not move — that is a same-hour problem, not a next-day one.
Details →Compressors, clutches, blowers and leak diagnosis. In a Valley August a dead cab A/C takes a truck out of service as surely as a mechanical failure.
Details →Engine oil and filters, fuel and air filters, plus the wear inspection — at your yard, on your schedule, without pulling a unit from rotation.
Details →Jump starts, battery testing and replacement, charging-system checks. We test rather than just boost — a jump that dies again in thirty miles has not helped you.
Details →We are not a shop that happens to answer the phone. The truck is already on the road — tell us your mile marker.
Don't see your town? If it's in the Valley or on the corridor, call — we almost certainly cover it.
The repair is the easy part. Getting paid at 2 a.m. on a dark shoulder is what slows everyone down — so we take every method a driver or dispatcher actually has.
Owner-operators: Zelle goes to (956) 560-5130. Dispatchers: call the same number and we'll take the code while the tech works.
Full payment instructionsIf you run trucks through the Pharr bridge or up the 281, a standing account turns a breakdown from a scramble into a phone call.
Account trucks go to the front of the queue. Your load is already late; the line shouldn't make it later.
Net terms and one consolidated invoice instead of a driver improvising payment on the shoulder at midnight.
We come to your yard on a schedule. The cheapest roadside call is the one that never happens.
RDZ Reliable Diesel Services is owned and run by Esteban "Lalo" Rodriguez. When you call at two in the morning, you are not reaching a call center that pages a contractor — you are reaching the person whose name is on the LLC.
That matters more than it sounds. A driver stranded on the 281 does not need a ticket number, they need somebody who already knows the road, knows the parts that fail on these engines, and has a reason to care whether the truck actually moves again.
We answer in English and Spanish, because in this Valley half the drivers on the road would rather explain a problem in Spanish — and getting the problem described accurately is half the repair.
Every mobile mechanic says they are reliable. Here is what you can actually verify before you call.
Typically 60 to 90 minutes anywhere in the Valley, faster near Pharr. Dispatch gives you a real estimate for your exact location before we roll — not a generic promise.
Yes. A person answers, 24 hours a day, 365 days a year. That is the difference between a service that says 24/7 and one that means it.
We tell you before we leave, not after. If the fault genuinely needs a shop, you get an honest read on the phone so you can call a wrecker instead of paying for a trip out.
Comchek, T-Chek, EFS, card or Zelle. Your dispatcher can authorize a fleet code by phone while the technician is still working, so nobody hunts for an ATM. Full instructions on our payments page.
Freightliner, Kenworth, Peterbilt, Volvo, Mack and International — engines, emissions, electrical, brakes, suspension, drive lines and A/C.
Yes — dispatch and the technician both. Describe the problem however it comes out easiest; that is what gets the right parts on the truck.
For scheduled work, fleet accounts and PM contracts, send the details and we'll come back to you. If your truck is down right now, call — don't fill out a form.
We'll get back to you shortly. If the truck is down right now, call (956) 560-5130 — that's always faster.
One call gets a live person, a real ETA, and a fully equipped truck headed your way. Any hour, anywhere in the Valley.
