Iron Brothers Diesel is a mobile diesel repair business in Southern Utah that also works on RVs. It comes to you, and its site says its technicians "will come to your location promptly." It does not publish a town or street address, so ask whether it will come to a campground outside Southern Utah.
It lists engine troubles, electrical issues, plumbing problems, fuel system problems, routine maintenance and diagnostics for motorhomes and travel trailers. It says it uses "advanced diagnostic tools to pinpoint the root cause" of RV problems, which is worth asking about before any parts are ordered. It does not mention air conditioners, refrigerators, generators or slide-outs, so ask about those first.
The trip fee is a "$100 call-out fee" during normal operating hours, and after 6 PM it is "$150 call-out fee + normal rate." Its rates list "$150/hr + call-out fee" for motorhome and RV work, against "$125/hr + $100 call-out fee" for normal operating hours. It publishes no hours, diagnostic fee or minimum charge, and it says "Call for local and contract pricing." Its "24/7 roadside diesel repair services" wording appears on its diesel roadside page, so ask whether that covers an RV at night. Call 435-218-2300 to ask.
It names no certifications, warranty, license, insurance, years in business or technicians. A license and insurance statement tells you the tech working on your rig is covered if something goes wrong, and a warranty tells you what happens if the same fault comes back, so ask for both. Google rates it 4.9 stars from 125 reviews.
This is a good fit for an owner in Southern Utah whose motorhome or travel trailer has an engine, electrical or plumbing problem and who wants the work done where the rig is parked. It is a weaker fit for a traveler who needs air conditioner, refrigerator or slide-out work.
