Before backing under a trailer, why should you check that the trailer's height is slightly lower than the fifth wheel?

Pick an answer

1. So the fifth wheel raises the trailer slightly as it slides underneath, locking on properly
2. It only matters for appearance once the units are coupled
3. A trailer that sits too low is always too heavy to couple safely and needs to be reloaded first
4. Trailer height has no bearing on how the coupling engages
