Hiring Diesel Technicians in RV, Marine, and Powersports

As demand continues to rise for Diesel Technicians in the RV, marine, and powersports sectors, employers are feeling the pressure. Whether you're managing a dealership, running a mobile service operation, or supporting a service center, one thing’s clear — skilled diesel techs are getting harder to find and even harder to hire.

To help businesses attract and secure top diesel talent, we’ve outlined what the job really involves, what today’s candidates expect, and how flat-fee recruiting can give you a hiring edge in a competitive labor market.

What Diesel Technicians Actually Do

Diesel Technicians specialize in maintaining and repairing diesel engines, fuel systems, and key vehicle or vessel components. Their skill sets vary based on the environment — think RV engine diagnostics, marine propulsion systems, or brake and suspension work on diesel-powered trailers.

Core Duties Include:

• Troubleshooting engine, electrical, and emissions issues

• Performing regular maintenance and compliance checks

• Rebuilding or replacing transmissions, turbo systems, and hydraulics

• Working in field service vehicles, dealership bays, or mobile units

These roles are hands-on, physically demanding, and often require adapting to industry-specific equipment and manufacturers.

Where Diesel Techs Work in Our Industries

• RV Dealerships & Repair Facilities

• Boat Yards & Marine Service Centers

• Powersports Shops with Diesel Utility Equipment

• Trailer and Mobile Service Operations

  
  

Many employers we support need techs who can handle both diagnostics and physical repairs — especially in environments where diesel engines are integrated with complex wiring, generators, or propulsion systems.

Certifications, Tools & Trade Training

While some techs gain experience through apprenticeships or on-the-job learning, many pursue certifications that increase their earning potential and hiring appeal.

Common Credentials:

• ASE Certifications for diesel repair and electrical systems

• Manufacturer-specific training (e.g., Cummins, Caterpillar)

• EPA 609 Certification for A/C service

• DOT Inspection or Air Brake Certifications (especially for RVs or trailers)

Many diesel technicians are also expected to supply their own tools, which is often a major upfront investment and a good indicator of their level of experience.

The Hiring Landscape for Diesel Techs in 2025

The latest data from the Bureau of Labor Statistics highlights just how tough the market is:

• 300,000+ open roles across the U.S.

• 25,000+ new openings every year

• Job growth holding steady at 3% through 2033

Within the RV, marine, and powersports space, demand is even tighter. Employers who need technicians with niche experience — like generator installs, hydraulic leveling, or marine diagnostics — are often stuck competing for a limited talent pool.

And it's not just about demand — it's about fit.

Why Hiring Diesel Technicians Is So Challenging

Here’s what makes diesel hiring uniquely tough for our industries:

• Specialization matters. A diesel tech with over-the-road truck experience may not have the skills needed for marine propulsion or Class A RVs.

• Unappealing shifts. Many roles start on second or weekend shifts, and newer techs are avoiding them.

• Job boards don’t work. Skilled techs rarely apply through ads anymore. They rely on word of mouth, referrals, and trusted recruiters.

If your job post has been live for weeks with no qualified applicants, you’re not alone — and it’s not your job description. The problem is visibility.
