Broken down in
South Texas?

Mobile heavy-duty repair for 18-wheelers, trucks and trailers across the Rio Grande Valley. Call any hour, day or night — we tell you honestly how long before we roll, then fix the truck where it sits.
Call Any Hour
Call any hour, day or night. Tell us where the truck is and we tell you honestly how long before we roll.

Based in Pharr, covering 12 cities: Pharr, McAllen, Edinburg, Mission, San Juan, Alamo, Hidalgo, Weslaco, Harlingen, Brownsville, Port Isabel and Falfurrias.

Zelle to (956) 560-5130. Fleet checks (Comchek, T-Chek, EFS) and cards: ask when you call and we'll tell you what works for your job.
Mobile Repair, Done Roadside
Everything below happens where your truck sits — the shoulder, the yard, the truck stop, the customer's dock.
Roadside Assistance
Breakdown calls any hour — jump starts, air leaks, and getting a dead rig off the shoulder safely.
Roadside details →Tire Services
Blowout on 281? Flat repair, tire change and air, in steer, drive and trailer positions. Tell us your tire size; we confirm we have it before rolling.
Tire details →Mechanical Repair
Brakes, suspension, drive lines and A/C — the repairs that normally mean a tow, done where the truck already is.
Repair details →Preventative Maintenance
Fleet PMs, oil and filter service, and DOT inspection prep — at your yard or the truck stop, on your schedule.
PM details →Trailer Repair
Doors, lighting and wiring, air lines, landing gear, kingpin and suspension — half the breakdowns in this Valley are the trailer, not the tractor.
Details →Brake & Air System
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 →Truck A/C Repair
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 →Oil Change & PM
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 Start & Battery
Jump starts, battery testing with replacement arranged, and charging-system checks. We test rather than just boost — a jump that dies again in thirty miles has not helped you.
Details →The Entire RGV & South Texas Corridors
We're a mobile service, not a shop. Tell us which mile you're at and we come to the truck.

The Makes We Work On Most
Paying Is Simple
Zelle works today. Fleet checks and cards depend on the job — ask when you call and we'll tell you what works. Dispatch tells you on the call when payment is due.
Owner-operators: Zelle goes to (956) 560-5130. Dispatchers: call the same number and ask what works for your job.
Full payment instructionsFleet Accounts
If you run trucks through the Pharr bridge or up the 281, talk to us before the first breakdown — so it's one phone call, not a scramble.
Regular Work
Talk to us about regular work for your fleet. Your load is already late; knowing your trucks ahead of time helps.
Billing Your Company
Ask about billing your company directly, instead of a driver sorting out payment on the shoulder at midnight.
Scheduled PM
We come to your yard on a schedule. The cheapest roadside call is the one that never happens.
You're Calling Esteban
RDZ Roadside is owned and run by Esteban “Lalo” Rodriguez. It's a local, owner-operated business — not a call center that pages a contractor.
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 trucks, and has a reason to care whether the truck actually moves again.
We speak Spanish and English, 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.
Straight Answers

Before You Call
How fast can you get to my truck?
Near Pharr, often under an hour. Farther out (Brownsville, Port Isabel, Falfurrias) takes longer, and we tell you honestly how long before we roll. Call (956) 560-5130 any hour, day or night.
Can I call in the middle of the night?
Yes. Call any hour, day or night. Tell us where the truck is and what it's doing, and we tell you honestly how long before we roll.
What if it can't be fixed roadside?
If it needs a shop, we'll tell you. Describe what the truck is doing when you call — it helps us give you a straight answer.
How do I pay?
Zelle to (956) 560-5130. Fleet checks (Comchek, T-Chek, EFS) and cards: ask when you call and we'll tell you what works for your job. Dispatch tells you on the call when payment is due. Full instructions are on our payments page.
Which trucks do you work on?
The truck makes we work on most: Freightliner, Kenworth, Peterbilt, Volvo, Mack and International — engines, emissions, electrical, brakes, suspension, drivelines and A/C.
Do you speak Spanish?
Yes. We speak Spanish and English. Describe the problem however it comes out easiest — getting it described right is half the repair.
Which areas do you cover?
Twelve cities: Pharr, McAllen, Edinburg, Mission, San Juan, Alamo, Hidalgo, Weslaco, Harlingen, Brownsville, Port Isabel and Falfurrias. That's along I-2/US-83, I-69C/US-281 and US-77 north to Raymondville. If you're near one of them, call.
Do you offer fleet accounts?
Talk to us about regular work for your fleet, including scheduled preventative maintenance at your yard. Ask about billing your company directly.
Do you sell diesel or red diesel?
No — RDZ doesn't sell or deliver fuel of any kind, including red (off-road) diesel. We're mobile diesel mechanics who repair trucks and trailers where they sit.
