Many of the new coaches I've seen recently at a local RV show were equipped with MORryde's StepAbove entry steps.
If I were to upgrade, I would definitely consider these as the stability is virtually night and day from the traditional pull-out chassis steps. And they're a bolt on application.
Here's the link to the product line and application guide.
