Red Rock Garage

Red Rock Garage is a diesel truck and auto shop based in St. George, Utah, that also works on RVs and trailers, and it runs both ways: you can bring the rig to its shop at 4204 S River Rd #A, or its mechanics will come to you. For mobile calls, the drill is simple: "Provide your location. Tell us when to meet you there."

On the RV and trailer side, it lists electrical system repairs, brake and axle service, roof and seal maintenance, and interior component fixes. It also covers diesel diagnostics, engine repair, routine maintenance, tire service and DOT inspections, which matters if your tow vehicle or motorhome chassis needs attention alongside the rig itself. Its mobile unit handles flat tire repair and replacement, jump-starts, minor mechanical fixes and fuel delivery, and it says its mobile and emergency work covers "the St. George area."

No trip fee, hourly rate or diagnostic fee is published, so ask about that when you call, along with whether a mobile visit fits your location. The shop offers "24 Hr. emergency roadside assistance for diesel truck and semi-truck repair and flat tires," and it says it has been serving St. George since 2005 with no appointment needed, first-come, first-served. It is also a Michelin authorized dealer and on call 24/7 for Michelin national accounts, useful to know if you are already running Michelin tires on your rig.

Google rates it 4.2 stars from 56 reviews.

This is a good fit for a traveler stuck on the road near St. George with a flat, a diesel problem or an RV system issue, or a local owner who wants a shop that also does the mobile call when towing the rig in is not practical.
