RVTI Level 1 Certification Exam 2025 –
Complete Questions with Verified Passed
Answers
Below are exactly 50 multiple-choice questions simulating the RVTI Level 1 Certification Exam
for 2025, based on the exam's format of a 2-hour written test covering RV systems (electrical,
propane, plumbing, chassis, appliances, safety). These questions are derived from RVTI
curriculum, industry standards (e.g., NFPA 1192, RVIA guidelines), and verified training
materials. Each question includes four options (A, B, C, D), the correct answer marked with
(Correct Answer: X), and a detailed rationale explaining why the correct answer is right.
Question 1: What is the primary function of the two-stage regulator on a propane
system?
A. To increase propane pressure for appliances
B. To reduce high tank pressure to a usable level for distribution
C. To filter impurities from the propane supply
D. To monitor propane levels in the tank
Correct Answer: B
Rationale: The two-stage regulator reduces the high pressure from the propane tank (up to 250
psi) first to an intermediate level (10-20 psi) and then to a low pressure (11 inches water column)
safe for appliances, per NFPA 1192 and RVTI Level 1 curriculum. Increasing pressure (A) risks
explosion, filtering (C) is the pigtail/filter, and monitoring (D) is the tank gauge.
Question 2: In RV electrical systems, what is the purpose of the 30-amp shore power
cord?
A. To connect to a 50-amp service only
B. To supply power from campground pedestal to RV converter/charger
C. To bypass the RV's battery system
D. To charge the chassis battery exclusively
Correct Answer: B
Rationale: The 30-amp cord connects the RV to a 30-amp pedestal, supplying AC power to the
converter for DC conversion and battery charging, as per RVIA standards and RVTI electrical
, module. 50-amp (A) is higher capacity, bypassing (C) not standard, chassis battery (D)
separate.
Question 3: What is the recommended torque for lug nuts on a typical RV chassis wheel?
A. 50-60 ft-lbs
B. 90-120 ft-lbs
C. 140-160 ft-lbs
D. 200-220 ft-lbs
Correct Answer: C
Rationale: Standard torque for most RV chassis lug nuts is 140-160 ft-lbs to ensure secure
wheel attachment without stripping, per manufacturer guidelines and RVTI chassis training.
Lower (A, B) insufficient, higher (D) risks damage.
Question 4: Which appliance in an RV uses the most propane during operation?
A. Refrigerator (on gas mode)
B. Furnace
C. Water heater
D. Stove/oven
Correct Answer: B
Rationale: The furnace uses the highest BTU rate (20,000-40,000 BTU/hr) for heating, per RVTI
propane/appliance module. Refrigerator (A) 1,800 BTU/hr, water heater (C) 12,000-20,000, stove
(D) variable but lower.
Question 5: What is the proper procedure for winterizing the RV plumbing system?
A. Drain tanks and add RV antifreeze to lines
B. Fill with regular automotive antifreeze
C. Leave water in system and disconnect hoses
D. Blow out lines with compressed air only
Correct Answer: A
Rationale: Winterizing involves draining and adding non-toxic RV antifreeze to protect pipes
from freezing, per RVIA winterization guidelines and RVTI plumbing section. Automotive
antifreeze (B) toxic, leaving water (C) risks burst, air only (D) insufficient.
Question 6: In RV electrical troubleshooting, a tripped GFCI outlet is most likely caused
by:
A. Overloaded circuit from too many appliances
B. Moisture in the outlet or connected device
