There are a lot of people who will work on your RV. Very few of them have formal training in RV-specific systems. The gap between an "RV handyman" and a credentialed RV technician is significant — and in systems like propane, electrical, and structural, it can be a safety issue, not just a quality issue.
Here's what the credentials actually mean, and how to find someone who has earned them.
The credentials that matter
RVTI (RV Technical Institute) is the industry's primary certification body. Technicians progress through four levels — Levels 1–4 — with Level 4 representing the highest degree of certified proficiency. RVTI training covers electrical (both 12V DC and 120V AC systems), propane, plumbing, appliances, slide systems, and chassis/structure depending on the level. An RVTI Level 3 or Level 4 tech has passed written and practical assessments. This is the credential you want for anything beyond basic maintenance.
NRVTA (National RV Training Academy) certifies both technicians and inspectors through a curriculum-based program with hands-on training. NRVTA-certified inspectors are specifically trained to identify defects and safety issues across an RV's full system — they're the people you want for a pre-purchase inspection or a post-repair verification.
RVIA (RV Industry Association) certification is administered through RVTI but the RVIA seal indicates the tech has met the association's training standards. You'll see this on some dealer service departments and independent shops.
None of these credentials are required to legally work on RVs, which is why you'll find a wide range of training levels among people who advertise RV repair services.
Questions to ask before you hire
Ask directly: "What certifications do you hold, and can I verify them?" A legitimate tech will be able to name their certification level and the body that issued it. RVTI and NRVTA both have online registries where you can confirm credentials.
Ask about experience with your specific system. A tech who specializes in Class A diesel pushers has a different knowledge base than one who primarily works on towable trailers. Ask how many repairs they've done on your RV brand and type, specifically.
Ask whether they use OEM parts or aftermarket, and whether the work is warranted. A confident tech will answer these questions directly. Vague answers ("I'll use whatever works") are worth noting.
Red flags
Be cautious of anyone who won't give you a written estimate before starting work, who quotes by the job rather than by time and materials without explaining the basis, or who won't pull necessary permits for propane or electrical work that legally requires them.
Also be cautious of "campground techs" who appear at your site unsolicited or who are recommended by the campground as the only option. Some are excellent; others are not. The credential question applies equally.
How SMART-RV fits in
The SMART-RV technician network is built exclusively around credentialed professionals — RVTI and NRVTA certified — whose submitted field cases are peer-reviewed by two other technicians before going live. When you find a tech through SMART-RV, you can see their certification level, their service area, and their field case history before you make contact.
The Find-a-Tech directory filters by location, certification level, and specialty. It's the fastest way to find a verified tech in your area without relying on forum recommendations or campground referrals.
