RVTI Certification Exam 2026 150 Questions – Propane Systems, Electrical, Plumbing, RV Maintenance Guide | RV Technician

This document contains approximately 150 exam-style questions with verified answers for the RVTI (Recreational Vehicle Technical Institute) certification exam. It covers essential RV systems including propane systems, electrical diagnostics, water systems, appliances, safety procedures, and maintenance practices, as presented across pages 1–15 of the document. The material provides a comprehensive and in-depth review of RV technician fundamentals, beginning with propane system operations such as regulator stages (first stage reducing pressure to ~10 PSIG and second stage to 11 inches water column), container positioning, and leak testing methods like timed pressure drop tests (pages 1–2 and 6). It also covers safety standards and handling practices, including avoiding tools like vise grips on propane tanks and proper purge procedures for new containers to eliminate contaminants like air and moisture (pages 2–3). Additionally, the guide explores electrical systems in detail, including AC/DC voltage measurement (vDC and v~), use of multimeters and clamp ammeters, circuit protection (fuses and breakers), wiring standards, and troubleshooting issues such as open circuits, loose connections, and “hot skin” testing procedures (pages 7–9). It also emphasizes safety protocols such as disconnecting the negative battery cable first and ensuring proper ventilation when charging batteries. A significant portion of the content focuses on water and plumbing systems, including leak detection through pressure testing, winterization techniques using bypass valves, low-point drains, anti-siphon valves, and troubleshooting low water pressure issues (pages 11–12). It also explains drainage systems, holding tanks, and proper maintenance practices for RV sanitation systems. The document further includes appliance and system operations such as furnace power sources (propane, electric, diesel), water heater components (ECO switch, anode rods), refrigeration thermistors, and generator operation and maintenance (pages 12–14). It also covers structural and mechanical aspects like slide-out systems, hitch ratings, braking systems, and seal inspections. Safety and compliance topics are integrated throughout, including fire extinguisher requirements (10B:C rating), escape requirements (maximum 20 lb force), and adherence to RVIA and DOT standards (pages 8 and 15). The structured Q&A format mirrors real RVTI certification exams, making it highly effective for practical exam preparation and field application. This document is closely aligned with RVTI certification standards and is commonly associated with RV technician training manuals and industry guidelines used in recreational vehicle service and maintenance programs. This document is highly relevant for students and professionals enrolled in: RVTI certification and RV technician training programs Automotive and mechanical technician courses Electrical and plumbing trade programs Recreational vehicle maintenance and service training Technical and vocational education programs It is especially useful for RV technicians, service professionals, mechanics, and students preparing for RVTI certification or aiming to develop hands-on expertise in RV systems, diagnostics, and maintenance.
