3 step replacement for 2 step on 335 Mountaine

[fulltimedreamer]

I need a source for a 3 step replacement for the 2 step unit that is at the bedroom exit on a 335 RLBS Mountaineer. The steps are approximately 22.5" wide. I have only seen 3 steps in 25-27" widths. It's a long way to the ground from the last step. I have considered adding a step or box on the ground at the bottom, but would like a folddown better. My dealer is not aware of a 3 step with the narrow width. Anybody here seen one of these?

Thanks.
