J & J Truck Service

J & J Truck Service is a diesel repair shop based in Gallup, New Mexico, and it does tire work too. It runs road service and will service "up to a 100-mile radius of Gallup, NM," which it names as including Mentmore and Defiance. You can also bring the rig to its shop on West Historic Highway 66. The shop does not say whether it works at campgrounds or driveways, so ask.

Its mechanics work on "medium-duty trucks, heavy-duty trucks, trailers, motorhomes, and buses." Motorhomes are the only RV type it names. The service list covers diesel engine and transmission repair, cooling systems, brakes, suspension, batteries, alternators, air filters, tire repair and state inspections. It does not name refrigerators, slide-outs or generators, so ask about those directly.

It publishes no hourly rate, trip fee or RV pricing. Ask about the trip fee when you call, and get the estimate in writing before any work starts. Its promise to "beat dealer prices" is worth testing against that estimate. It advertises "24-Hour Call-Out Service" for after-hours trouble, but it does not show store hours.

It has been in business "for over 20 years" and calls its mechanics "highly qualified." It names no certifications, no licensing or insurance statement and no warranty. Ask which credentials the tech holds and what the repair is warranted for, because a warranty is what backs the work after you drive away. Google rates it 3.9 stars from 159 reviews and lists it as a truck repair shop.

This is a good fit for an owner near Gallup, Mentmore or Defiance with a diesel motorhome who needs engine, drivetrain or tire work and wants a quote first. A traveler well outside the 100-mile radius should look for a closer shop.
