Master Certified RV Services

Master Certified RV Services is a mobile RV tech based in Cedar Rapids, Iowa. It comes to you, at the campground, in storage or at home, so you never have to leave the campsite for the repair.

Jim Pettry, the owner and operator, works on motorhomes, fifth wheels and travel trailers. He handles roof leaks, batteries, air conditioning, water system repairs, blue and black tank maintenance, leak detection, slide-outs, awning motors, electrical repairs and water heaters, including Aqua-Hot systems. He also offers end of warranty inspections and pre-purchase RV inspections, along with full RV orientations for owners new to a rig, and custom work like solar, inverter and generator installs.

No hourly rate or trip fee is published, so ask about both when you call. On-site estimates are offered, and "the estimate fee will be waived upon completion of the repair," which means if you move forward with the fix, you are not paying twice to find out what is wrong.

Pettry is a US military veteran and a certified technician through the RV Technical Institute, the National RV Training Academy and RVDA/RVIA. Those certifications matter because they mean the person showing up at your site has trained specifically on RV systems, not just general vehicle repair. Google rates the business 5 stars from 31 reviews.

This is a good fit for an owner who wants repairs done without breaking camp, a traveler whose slide-out or AC has quit mid-trip, or someone buying a used RV who wants an inspection before signing.
