a pair of side rails oriented parallel to one another, each side rail having a first longitudinal end and a second longitudinal end;
a first step spanning between the pair of side rails;
a second step spanning between the pair of side rails, the second step arranged between the first step and the second longitudinal ends of the pair of side rails
a pair of mounting flanges, wherein each mounting flange extends from the first longitudinal end of a respective one of the pair of side rails, each mounting flange defining an aperture through the flange in a direction perpendicular to a longitudinal axis of the pair of side rails; and
a mounting plate, the mounting plate including a flat base portion and a support flange, the support flange extending perpendicular from the flat base portion at a longitudinal end of the flat base portion,
wherein the mounting plate includes a pair of hinge tabs, each hinge tab configured to receive a portion of a respective one of the support flanges such that the aperture in each of the mounting flanges aligns axially with each respective hinge tab, and
wherein the first step is located relative to the first end of the pair of side rails such that a bottom of the first step can rest atop a bumper surface of the utility van when the stair assembly is in a deployed state.
