1. A ladder assembly for a vehicle, the ladder assembly comprising:
a platform having a thickness defined between a top side of the platform and an opposite bottom side of the platform;
a ladder pivotally mounted adjacent the platform via mounts, wherein the ladder is rotatable between a deployment position and a storage position, the ladder has a length defined between a first end of the ladder and an opposite second end of the ladder, and, when the ladder is in the deployment position, the first end of the ladder extends above the top side of the platform and the opposite second end of the ladder extends below the opposite bottom side of the platform;
an actuation mechanism comprising a drive configured for linear movement from a first position to a second position;
a rotational actuator operatively connected to the ladder, wherein the drive of the actuation mechanism engages the rotational actuator such that linear movement of the drive from the first position to the second position rotates the rotational actuator to pivot the ladder about the mounts; and
a ladder support mountable to a top of the vehicle and comprising an attachment portion for attaching the ladder support to a roof of the vehicle, a support arm for supporting the ladder when the ladder is disposed in the storage position, and alignment members located on the support arm for aligning and holding the ladder during operation of the vehicle such that, when the ladder is disposed in the storage position, a portion of the ladder engages the alignment members located on the support arm of the ladder support that is mountable to the top of the vehicle
wherein
the rotational actuator includes a shaft,
the ladder is pivotally mounted to the mounts and connected to the mounts via a pivot pin, and
an axis of the shaft and an axis of the pivot pin are in alignment.
