Joe's Master Service Center is an auto repair shop based in Edinburg, Texas, that also handles RV chassis and undercarriage repairs. You bring the rig to its shop on N. Closner Blvd, since this is a fixed location rather than a mobile service.
On the RV side, it works on chassis and undercarriage systems to keep a motorhome road-ready. It also covers brake inspection, service and repair, suspension and steering repair, A/C repair, electrical repairs, and tire sales and service, all of which apply to a motorhome's running gear even when the job started as an auto repair. The shop serves Edinburg, McAllen, Hidalgo County, Pharr, Mission, Palmview, Penitas, Granjeno, Perezville, Abram and Palmview South.
No RV-specific pricing, hourly rate or trip fee is published, so ask about cost when you call. Hours run Monday through Friday from 8:30 AM to 6:00 PM and Saturday from 9:00 AM to 3:00 PM, with early drop-off and after-hours pick-up available for a busy schedule. It also offers financing through Synchrony, EasyPay and Snap, which can matter if an undercarriage repair runs higher than expected.
The shop has roots going back to 1964 in Edinburg as Joe's Texaco, and it backs its work with a parts and labor warranty, something worth asking about before a chassis repair since it means a come-back job on the undercarriage is covered. Google rates it 4.3 stars from 472 reviews.
This is a good fit for an RV owner based in or passing through the Rio Grande Valley who needs chassis, brake, suspension or A/C work done at a shop rather than roadside, and who wants financing options on the table before committing to a repair.
