An RV technician is part electrician, part plumber, part gas fitter and part mechanic, all working inside a house on wheels. You do not need a degree. Shops hire motivated beginners and train them, so your fastest path is to learn the basic systems (12-volt DC, 120-volt AC, propane, water, brakes and chassis), build a hands-on habit of testing before replacing parts, and then earn RVIA/RVDA technician certification. This roadmap takes you from safe basics, to a shop-ready tech who can diagnose furnaces, AC units and leaks, to an advanced tech who handles slide-outs, hydraulic levelers, generat

Stage 1 of 1 · about 10 weeks
Understand how an RV's systems fit together, use basic tools and a multimeter safely, and do simple inspections and repairs under supervision.
Shop safety and RV systems overview
RVs combine propane, high-voltage AC, battery DC and water in a tight space. One mistake can cause fire, shock or carbon monoxide poisoning, so safety habits come first. Knowing how the systems connect also makes later diagnosis far easier.
Basic electrical: 12V DC and 120V AC with a multimeter
Most RV complaints, such as lights, pumps, fridges and slides, are electrical. If you can measure voltage, continuity and resistance, you stop guessing and start diagnosing. Ohm's law (V = I x R) and power (W = V x A) explain why wires overheat and fuses blow.
Plumbing and water systems
Water leaks ruin floors and walls, so leak repair is one of the most common warranty jobs. You need to know the fresh water pump, PEX and fittings, water heater, and drain systems.
Propane (LP gas) basics
Propane runs the furnace, stove, water heater and often the fridge. A leak is a fire and explosion risk, so you must understand regulators, pressure and leak testing before touching gas lines.
Customer communication and work orders
Your top skills are listening and speaking. A clear work order tells you what the customer actually experienced, which often points straight to the fault. Good notes also protect the shop on warranty claims.
