Abstract

The step supports brace and stabilize retractable stairs used in recreational vehicles, while accommodating uneven ground beneath other recreational vehicles doorways and the various heights of the bottom stair step above the ground. The step supports are configured to be used in one of two different upright orientations resting atop the ground on one to two base ends of the support. The step supports include a plurality of integral support blocks defined and separated by two sets of vertical channels that receive the bottom stair step for each orientation. In each orientation, the bottom stair step is seated within one of the vertical channels and is braced between two adjacent support blocks. The dimensions of the step support end walls and the uniformly spaced support block allow the step supports to be selectively oriented and positioned to brace and stabilize the stairs at incremental heights above the ground.
