ABSTRACT:
A ladder assembly including a mounting system and a ladder that is adapted to be pivotally attached to a vehicle such as the tailgate of a truck bed. When the tailgate is opened, the ladder can be pivoted away from the vehicle bed to a substantially perpendicular position with respect to the tailgate or its original orientation. Following, the lower end of the ladder is adapted to pivot downwardly such that the lower end of the tailgate contacts the ground surface. The ladder is further pivotable about a second pivot member in a lateral manner such that the lower ends of the support legs of the tailgate ladder contact the ground depending on the slope of the ground surface.
