My trailer has the two step version. They are only about 8 inches deep and they have about an inch of overlap. So, going up, I can use the whole thing. But, going down, unless I drag the backs of my heels, I have less than 7 inches. And, when my foot slips past the 1st step, my toes are already past the second step, so I just ski right past it too.
The stand-alone plastic steps are an option, but I'd still need some really deep ones.
