1. What is the most important number to check when determining the weight bearing capacity of a specific truck?
A) Towing capacity
B) Gross Combined Weight Rating (GCWR)
C) Payload capacity
D) Fuel economy
Correct Answer: C
Explanation: Payload capacity determines how much weight the truck can safely carry in the bed, which is critical for truck campers.

A) Behind the rear axle
B) In front of the front axle
C) Over or in front of the rear axle
D) Anywhere if tie-downs are secure
Correct Answer: C

A) Check the towing guide
B) Look up the manufacturer’s curb weight
C) Search Google for the answer
D) Check the yellow “Tire and Loading Information” sticker on the driver’s side door jam
Correct Answer: D
Explanation: The yellow “Tire and Loading Information” sticker shows the actual payload capacity of a specific truck as built.
4. Which factor most commonly reduces a truck’s payload capacity below what buyers expect?
A) Fuel tank size
B) Four-wheel drive option
C) Engine, cab, and trim level options
D) Color and wheel package
Correct Answer: C
Explanation: Trim options like four-wheel drive, larger cabs, and premium packages add weight, reducing available payload.
5. Why do slide-out campers typically weigh more than non-slide models?
A) They require more insulation
B) They are longer and wider
C) Slide mechanisms and structure add significant weight
D) They include more tanks
Correct Answer: C
Explanation: Slide-outs add mechanical components and structural reinforcement, increasing total camper weight.

A) Lower profile and better fuel mileage
B) Higher insulation value
C) More interior space
D) Larger fresh water tanks
Correct Answer: A
Explanation: Pop-up campers have a lower profile when in the travel position helping with handling and fuel economy.
7. What is RAWR (Rear Axle Weight Rating)?
A) Maximum weight allowed on the rear axle
B) Curb weight of rear wheels
C) Weight distribution with trailer
D) Payload subtracted from GVWR
Correct Answer: A

8. Why might a crew cab short bed have less payload capacity than a regular cab long bed?
A) Shorter bed
B) Smaller wheels
C) Heavier cab and trim level
D) Lower suspension rating
Correct Answer: C
Explanation: Crew cabs are heavier, leaving less available payload than regular cabs. Higher trim levels also add weight further reducing payload capacity.
