The Truck camera animation makes the camera move horizontally between two keyframes (in the camera reference frame) by modifying the camera's position and target point in a parallel way. This can be useful when you want to move the view (both the camera's target point and position) along some system in a horizontal direction.
Truck camera and Pedestal camera animations act in the same way while moving the camera in the horizontal and vertical directions, correspondingly.

Adding the animation
First, choose the start frame in the Animator's Track view and orient the view/camera as you would like it to be positioned.
Then, double-click on the Truck camera animation effect in the Animation panel of the Animator.
The camera's target point and position are used for the start frame and for the end frame both of them are shifted horizontally to the right by the same distance.
Set the end frame of the animation as needed.
Note: You can always move the start and end frames of the animation.
Properties
By default, camera animations are applied to the active camera (to change that, inspect the animation and modify the "Apply to active camera" option). So, the target point of the animation will be defined as the current target position of the active camera, which is basically the current center of the view.
The camera positions might be defined differently whether you have the grid in the viewport switched on or off. To change how the animation behaves depending on whether the grid is on or off, inspect the animation and modify the "Keep camera upwards" option - if this option is checked then it will depend on whether the grid is on or off.
You can also change how the camera's parameters are interpolated between the frames by modifying the Easing curve.
Adjusting camera positions
You can adjust the camera's target points and positions using the animation controllers. See Adjusting camera positions.
Note: The Truck camera animation has some special limitations on how the camera's target points and positions can be adjusted.
