To drive, how much should the landing gear be raised?

The correct approach for raising the landing gear is to do so completely until it is secured. This is essential for several reasons. When the landing gear is fully raised and secured, it prevents the gear from dragging on the ground during transit, which can cause damage to the gear itself and create safety hazards. If the landing gear is not fully retracted, it can also interfere with maneuverability and increase the risk of accidents, especially during tight turns or when navigating uneven terrain.

Additionally, a securely raised landing gear signifies that the trailer is properly attached to the truck, reducing the risk of disconnection or instability during travel. Ensuring that the landing gear is raised completely enhances overall vehicle safety and performance, making it a critical step in the pre-trip inspection and preparation process before hitting the road.
