01Occupational Safety, Tools, and Trade Practices
This domain tests whether you can work on an RV without harming yourself, the customer, or the unit, and whether you choose and use tools correctly. Expect questions on hazard control, lockout/tagout, WHMIS/GHS labels and safety data sheets, ladder and roof work, LP and carbon monoxide hazards, battery and 120 V shock hazards, torque practice, fastener selection, and the paperwork that records it all.
502 words, about 3 min02Electrical Systems (12 VDC and 120 VAC)
An RV carries two electrical systems that share a chassis: 12 VDC house and chassis circuits, and 120 VAC shore, generator, and inverter circuits. The exam tests Ohm's law and voltage drop, battery chemistry and charging, converter and inverter behaviour, shore power configurations, bonding and grounding, overcurrent protection, and disciplined diagnostic method.
493 words, about 2 min03Propane (LP) Gas Systems and Appliances
LP questions test the physical properties of propane, containers and regulators, pressure testing, appliance operation, and combustion safety. This is the domain where a wrong answer is also a real-world explosion risk, so expect specific numbers.
467 words, about 2 min04Plumbing, Water, and Sanitation Systems
This domain covers fresh water supply, waste water, and everything between: pumps, heaters, tanks, valves, vents, and winterizing. Exam items focus on how each subsystem behaves under pressure, what happens when it is neglected, and the correct sequence for service and storage.
435 words, about 2 min05Heating, Ventilation, and Air Conditioning
HVAC items cover rooftop air conditioners, heat pumps, DSI furnaces, thermostats, and ducting. The exam wants you to read pressures, temperatures, and amp draws as evidence, and to follow the furnace ignition sequence in order rather than guessing.
466 words, about 2 min06RV Structure, Body, Roofing, and Sealants
Structure questions concentrate on water: where it enters, how it travels, and how to stop it permanently. You are also expected to know roof membrane types, the sealants approved for each, and how laminated sidewalls and floors are built.
425 words, about 2 min07Chassis, Running Gear, Towing, and Hitches
This domain covers weight ratings, hitch setup, trailer brakes, wheel bearings, tires, and axles. Exam items are usually arithmetic you must do correctly: payload, tongue weight, and gross combined weight all matter, and the lowest rating in the chain governs the combination.
451 words, about 2 min08Slide-Outs, Awnings, and Leveling Systems
This domain tests the mechanisms that move and support the coach body: slide-out rooms, awnings, and leveling systems. Expect questions on mechanism identification, synchronization procedures, safe manual override, and the difference between leveling and stabilizing.
450 words, about 2 min09Diagnosis, Repair, and Customer Service
The final domain tests how you think and how you communicate. Questions present a complaint and ask for the next diagnostic step, the correct documentation, or the right thing to tell a customer.
