Attaching a cargo carrier to rear 4x4 bumper

[AmeriLite21]

I am thinking of attaching a bolt on bumper hitch for a cargo carrier on the rear bumper of my AmeriLite 21MB. I want to carry a set of steps on the carrier. Total combined weight of the carrier and the steps would be less that 100 lbs. Has anyone attached anything to their rear bumper. Will the bumper hold the 100 lb weight? I am slightly disabled and assembling and disassembling the steps is really a hassle. Any comments would be appreciated.
