A ladder assembly for a pick-up truck is pivotally connected with the truck tailgate for movement between a stowed position where the ladder assembly is held against the tailgate and an operable position when the tailgate is lowered and the ladder assembly extends between the tailgate and the ground. A linkage assembly connects the ladder assembly with a mounting plate connected with the tailgate. The linkage assembly spaces the ladder assembly from the tailgate when the ladder assembly is in the operable condition, allows the angle of the ladder assembly relative to the tailgate to vary in accordance with the height of the tailgate relative to the ground, and prevents the ladder assembly from pivoting past a normal position relative to the ground. A handle is also pivotally connected with a side wall of the truck adjacent to the tailgate to assist a user with climbing the ladder assembly into the bed of the truck.
